Hide the field in the action related to the transaction "create working relationship"

Hello everyone!
We have a problem in hiding this field in some sections. We created it with "Page Composer" in the "Create Working Relationship" transaction, but we only want it to show up in the "intra-group posting" action. How do we hide it from the other actions that are associated with the "create working relationship" transaction?
Thank you for your help.
Mario.
