SuperMerger for Google Docs
It's a bird...no...it's a plane...no...it's SuperMerger for Google Docs (sorry, couldn't resist!).
This Google Sheet and Script will allow you to take merging to the next level. Make documents from a template containing merge codes, merge in the information...let the users interact with the document and....merge more information or add in another template. Great for weekly or monthly check ins or feedback. Provide some information, the user writes some responses and then insert more information into the document!
