"Mail Merge" in M-Files


I've searched for ideas, but as it looks like, no success so far.

I have a document Letter. On that document is a property definition (multi lookup) Recipients. When the Letter is in the WF state Print, for every recipient should be printed its own copy - the dynamic fields Company Name, Address, City etc. should be filled appropriately. Something like Mail Merge in MS Word, where you prepare one document with dynamic fields.

Any ideas?

Best, Uros
