Combining Pop Up! plugin with the who sees ads contexts?

can’t test this right now so I have to ask:

is there only one pop-up I can set up at any time?

if so, how about combining this plugin with the who sees ads contexts?

I’d love to be able to show one pop-up to visitors coming from search engines, none to people coming from another referrer and a 3rd one to people who have commented.

Kinda just like who sees ads but with a pop over.

can that be done/added to this plugin? shall I open a feature request?
