I wouldn't know how to achieve this without a plug-in, but you could use the FREE ScriptMaster plug-in (360Works.com) to accomplish your goal:
Here's a link to a solution that utilizes ScriptMaster:
Note: You will need an inexpensive subscription to FileMaker Magazine (a digital mag) to view the video, but you'll find this brings lots of additional and valuable content ...
Not with a plug in?
Use Acrobat and do it manually
But then that probably isn't what you meant.
In FMP will need a plug in.
ScriptMaster needs you to write you own Functionality (not for the faint hearted but V powerful)
Monkeybread plug in will do it
Productive computing have one too
Depends in use case, time, money, ability, desirability.... Usual criteria
Just one note:
In this particular case, you don’t need to write your own ScriptMaster code for merging PDFs, as Matt Petrowsky has done it for you …
Although I’ll admit, you have to put the pieces together correctly to make this work …
