Ah that's true. Maybe this replacement could work with some serious
limitations then but it sounds very messy / error prone.
Maybe a better question, how would you do what I'm trying to accomplish -
especially since you're part of the Adobe ecosystem?
This might be veering towards InDesign Server stuff, but I have designs
that start in Illustrator and I have 1-5 colors (like a theme) that I want
to swap out programmatically from the server. I start in Illustrator and
ultimately end up with a PDF to print but maybe there's some other flow in
between that would accomplish this better since PDF is obviously not meant
to be manipulated.
Thanks again for your input! It's very helpful.
