All, I need some inspiration as to how to make an intuitive way for users to edit a related record.

The issue at hand is, that users per default are working with Form A in Report A.
In form A there are relationship with form B.
Users would often have to edit and amend the data in Form B while they work in Report A.

However, as the current behaviour in ZC5 is that you can only view Form B, I am looking for ideas to a user friendly way of accessing and editing the related Form B. 

Mock-up of the missing edit button for inspiration.
