Permission to see PART of document

Hi I have been working with mayan for some time, and I find myself in the need of doing the following (its easier to explain with an example):

  • the document enters a state, in which 2 new roles now have access to see, add comments and files to that document

is there a way, in which, if one role adds a file (or a comment) it can’t be seen by the other role? and vice versa?

the idea is that those 2 roles get access to the document to do stuff, but they can’t see what the other role does (while an admin role can see all, in order to later pass it to another state)
