Basic Help with Rollable Table Tokens

I've read the Wiki on Rollable Table Tokens several times and I don't get it. I've tried searching the forums too but it seems everyone who needs help managed to get a little further into it than me before getting stumped. This is my first time using a rollable table at all so I'd like to use that as the excuse for my predicament. In Matrix style, I have created a "Loading" page for myself which is just a white background with a bunch of tokens assigned to the correct character sheets and with all the bubbles set up for hp & ac. I was figuring a rollable table would save me time rather than going to my loading page to copy the token then back to the screen my players are on to paste it. I have a few characters who would use this feature, but my example will be my rogue player who uses disguises. I have two tokens on my loading page, his base appearance and a disguised one. They both link to the same character sheet. Both tokens are not the same size. His disguise uses some padding to appear bigger and I had to make the token a little larger than standard 1x1.  When creating the rollable table item I can upload an image. I can't seem to drag an existing programmed token onto here. I can yank a .png file from "My Library" and put it in here. I tried uploading both .png files for his tokens in this manner. After saving, when I click the "Token" button on the rollable table, it drops the first .png file as a 1x1 token on my VTT. This token is not linked to a character sheet nor are the bubbles assigned to any stats. At what point, or how, do I assign these images in the rollable table to character sheets? And is there any way for me to have different "sides" of the token be different sizes? Any help is appreciated!

Once you’ve created a Rollable Table Token in the manner described, it is in a state as if you just dragged a graphic to the table top. You would now follow the normal steps you would for any graphic to set it up for a character(double click it, set who it represents, set what its bars are linked to, etc) with one caveat: you must right click it and turn off is drawing. This allows it to snap to the grid and lets it show bars. Be sure to set the completely set up token as the default token for your rogue. There isn’t a way to have the graphic size change based on the side of the token without an API script (Pro subscriber perk). You can download the images and scale them in an art program so they are visually different in size while having the same outer dimensions. This might involve matting the smaller image on a larger transparent square. 

Aaron to my rescue again! Now it makes sense that I need to set up the stats after and then tie it to the character sheet... I spent all this time thinking I was missing something in the setting up the table itself. Thanks for explaining it.
