How to export/import processes from command line?

I would like to source control all the processes (OneIM v9.2)

There is of course the GUI option:
How to export processes (4328025)

Although this is a nice feature i would like to do this from the command line (scripted bulk export of all processes)
But as far as I'm aware, there is no option to do so.
If so has this ever been requested for future enhancement?

Thank you,
Niels
