It would be really nice if we could link documents that are already uploaded to the clients contact card to a new note. Right now, if I want to make a note regarding a document that's already existing on the client's contact card and attach the document for easy reference (for example, a trust document), I have to download the document from the client's contact card, and then re-upload it via the note. I then have to re-name it, and re-tag it, and we then have duplicates of the same document on the client's contact card.
Being able to link existing documents would increase efficiency, and would keep our documents sections cleaner.
