Merging PDF pages

The short answer is NO. There is nothing built into Livecode to take a 
set fo existing PDF files and append them to create a readable PDF that 
is them all stitched together. Neither the XPDF external nor the PDF 
widget will do this.

You best option is to use some 3rd party command line utility that will 
merge PDF files that works on the platform or platforms your want to do 
this on and use the Livecode shell() function to call that command line 

If this is going to be a distributed standalone, you can actually read 
the utility as a binary file and compress it as a staved property in 
your application, that can uncompress and install it on any target computer.

We do this with the popular free open-source video tool ffmpeg for macOS 
and WIndows. Our app install it if needed on the target computer from a 
compressed copy bundled into our app and we use SHELL() to call it to do 
several video operations that can't be done in Livecode.
