Character Macro Help

I was thinking of trying the D&D 3 Pillar system. But I was looking to see if there was a way to make a Macro, where I might be able to click get a Character Query then have it maybe put 1 xp or 5 xp, whatever the button macro is set to give, to a Character sheet exp area. If targeting a Character sheet isn't an option maybe a Token Macro that sends it to that tokens sheet. I would like to be able to grant individual Exp on the fly type of thing.

Basic macros cant alter values on character sheets or tokens, they can only report results to chat. API scripts can do this, and you're a pro user, so you can use them. There are experience tracking scripts already made that can probably do what you need.  Failing that, you can do it with ChatSetAttr too.
