I unfortunately doubt command missions will have any new dungeons added to them... ever.
The devs have said that to make command missions work they had to program the AI to interact with each dungeon it can go into, as opposed to Trusts which were made to be able to largely function in whatever content they're brought into.
Because of this I doubt we'll see more done with command missions unless they figure out how to retrofit Trust programming into squadrons : (

I'd love to see it happen.
