Tagging a Writer document from within Writer and not Workdrive

Tagging a Writer document from within Writer and not Workdrive

I have successfully tagged documents in Workdrive. I'm using most of the Zoho apps (Writer, Sheets, Show etc).
Is it possible to change, create Tags from Writer and have them up[dated in Workdrive or are they a seperate DBase?

If it's not possible, is it on the Roadmap?
