Some of our users need to be able to edit certain documents while others don't. Can we add individual contributors to files within the documents module of Zoho CRM? I've been trying to find how to do it, but I can't seem to find the right combination of steps... In this case, we're using a Zoho Sheet which I want to lock portions of for certain people. I found the lock/unlock cells/sheets portion, but I can't find the way to add people to the list that is displayed.

Thanks for the help!
