Mail Merge Multiple Documents At Once, Albert Kallal

Hello,

I am currently using Albert Kallal's (Awesome) mail merge.

I am looking for a way to select multiple documents from the word Merge Templates list and merge them all at once. Mail merge is a significant portion of what my company does and finding a way to merge all of our documents at once would be HUGE!

I have been told that I need to allow multi-select in the selection listbox. But the coding is a bit over my head...

If you know what segment of code needs to be altered (something I can search for), or a forum that has this solution I would be very gratful. I have been looking for a while now and not had any luck.

Thank you,
