Grid and ER Diagrams Teamwork Client Revisions

Hi,
We have purchased Visual paradigm modeler, standart and team server for a team with 30 professionals, who are drawing diagrams with agile method.First we use Grid diyagram for our table, after that we want to create ERD from Grid table.
First, when we make changes to the Grid with Branch, we can’t see the diagram name or the grid name in Revisions. Is it possible to add diagram or the grid name that we can see the revisions.
Second, when we make changes to the Grid or ERD with Branch or non Branch, we can’t see the version before the changes. We only see new changes. Is it possible to add the version before the changes to the Teamwork Client → Revisions.
