I’m guessing that if you need your teammates to be able to select any two pdfs they want, then that will need to be programmed into the UI and isn’t currently available.
But before going that route, is that what you need? Or are you talking a limited number of combinations of pdfs here? If so, why not combine them outside of PTXprint and then just import the combined file. I’d do this using pdftk file1.pdf file2.pdf cat output newfile.pdf
, but I’m sure there are easy ways to do it in Windows too.
Alternately, it’s probable that this could be done with some sort of sethook. The disadvantage of that is that the location of the pdfs would need to be inserted into the code as a text string (not a nice GUI interface). Is that something you could set up, or within the ability of your teammates?
