Design program for Primitive mechs

[Red Pins]

I have a new project its time to start making units for, but most of them are drones and Primitives, with the usual cutting-edge Introductory and Jihad era units.  I downloaded Megamek Lab thinking it could do Primitives, but can't figure out how to do it.

So, does MML actually do Primitives?  I can get P-armor, but not engine, cockpit, etc..  If not, is there one that does?

yes it does

file --> switch unit type --> primitive / retro
