Feature Request - Multi-Line Field in Actions for Macros

Hello,

It would ne create to be able to use a custom ticket field (multi-line text fields) as an action in Macros. We utilize this field type for "Resolution Notes". It's required that our agents fill this in to give an overview on what they did to resolve the issue. This is helpful for understanding internal knowledge base articles, reporting, training, etc. 

Anyways, an agent was wanting to see if a Macro could update that field with the comment text posted when a macro solves a ticket. Unfortunately, we aren't able put this field in the actions place. It would be great to have this feature. Thanks!
