Using different colored W6, invisible units and export campaign?

Hi everyone, Im a really newbie and search a way to play the alien roleplaying game with friends. Currently i take a look on roll20 and have some questions. 1. Alien RPG use different colored W6 for stress rolls and  ability rolls. For example an attack has 4w6 from ability ranged attack and 6w6 from stress. Can i roll all 10w6 and have different colors on the 3d dice? 2. Is there the ability to hide tokens that only GM can see them to reveal them later? Is there a way to loop a ping simulating some sort of motion tracker? 3. When my OneShot is done, is there a way to export the whole campaign with all maps, tokens, music and charackter sheets to make them usable by others without selling them? 

1: For the different colored dice you would have to make a rollable table token . 2: If you put tokens on the GM layer then the players will not be able to see them but the GM can. Looping a ping is not possible that I know of unless you can do it with an API script (pro subscription feature). 3: Short answer: No. Long answer: You would have to use all original content (art, any music, and the text) then contact the Roll20 team for them to review it then set a price as they believe all content creators (the game's creator) should be compensated for their work. This is why there is almost no free modules.
