Pop Up Pro Logic/Prioritization and Pop Up by Author?

Hi,

How does Pop Up Pro work when you have multiple Pop Ups running that could be on the same page/post? For example, if I have a pop up set for all pages and then one set for just a specific page (let's call it Post A), what happens when the user visits Post A? Will they receive the global pop up AND the specific one for Post A or just the one for Post A? If I only want the specific pop up for Post A to show up, do I have to exclude that page from the global pop up?

And, is there a way to set the Pop Up by Author? Similar question, if there is a Pop Up by Author or Category and a global Pop Up, with both show if the categories are not excluded from the global pop up?

Thanks!
Jesse
