Importing different style character sheets

Hi! I was trying to figure out if there was a way to upload my own character sheets within roll20. Not a "this is my pc stats & I want her in this game" sheet, I mean a blank template. It's literally a variant of the normal 5e sheet that I prefer to use and I'd love to have it online. I have them in PDF form, just not sure how to upload them so I can pick them as a choice on the dropdown; or if that's even possible. Sidebar: If that is possible, can you also upload something like a "folder" of sheets so each character can choose the template they like most?

They need to be coded into CSS and HTML for upload into a game. If you have a pro account you can do your own, but you can't just load a PDF.

If you do decide to go the route of building your own sheet and get a pro subscription, read this:  Building Character sheets first to help make your decision.

And currently, you can use only one character sheet template in a game.
