To move many pieces

I am tempting to set a button to command the contemporary movement of a number of pieces with the same characteristics.
I copied the technique from the AH Submarine module where the command moves all ships in a convoy one hex.
Now I have some pieces that I move independently and all the others that I can move together with the command.
So I have to identify all the pieces that “haven’t moved yet”.
How can I do?

Well … resolved. I started using the technique of Submarine (AH) convoy move foreword command, that marked all the Convoy ships with a fixed Marker to identify the torpedoes, I added a layer for an additional marker used automatically at the launch, an additional button to remove this “first turn move” marker, so after the launch turn they can be commanded with all the others together.
