Add Dossier item (with folder) action

Hey together,

Sometimes we need to add a dossier item in background or via additional form button.
In the sublist that belongs to the dossier, it's not that easy to create the necessary folder or set the lookup column for the correct connection.

So, it would be very helpful to have a custom "Add dossier item" action that will created the dossier item and the according sublist folder / set the lookup.

Many thanks and best regards
