is Diagrom can be executed from workbench ?

Hello
I would like to know if it's possible to launch diagrom from workbench ?
I ask because I make 2mb rom custom with workbench inside for repair and troubleshoot system, I enable serial connexion for a shell, and from this, I can launch any program.
In case I don't have no video, my aim is to launch diagrom remotely by serial, so I need a exec.
Is it possible ?
Thank you
Regards
