Batch automate combining groups of PDFs in a folder

[bob_r7marketing]

I need to find a way to automate this task.
Hopefully within an Adobe application, but I'll take what I can get.

Starting with a folder containing many 1-page PDF files.
Combine specified quantity of files, in order of file name/number, into multi-page PDFs.
Example: I have a folder containing 100 1-page PDF files.
I need those files combined into multipage PDF files in increments of 12,

resulting in eight 12-page PDF files, and one 4-page file (combining the remaining 4 files).
These would be saved in the same folder, named in numerical order.

I've developed a (paid-for) script for Acrobat Pro that does that:

It can be customized to split the merged file based on number of pages, if you wish.
