A: Yes, you can do it - but you have to get a 'bit' creative. You will need to create 'multi-step' pop-ups for this. So, if a user wishes to go to a different URL, you can warn the user via a popup. Of course, there's the exit intent system you can set up (but that's really not applicable here). So, the general answer is yes - but you need to get a bit creative to make it happen.
