Custom Chassis / Blade system device #3148

Hi!

So, the question is quite simple, is possible to create a custom Chassis device which function like the two included "Blade Chassis" devices?

In particular, I'm running an HPE C7000 BladeSystem, so I tried to create a custom 10U Chassis, but I wasn't able to find a way to define the blade slots, so I suspect this is something related to the specific device already included?

I believe this may be related to this #159 but just wanted to check if I need to wait a little bit more or if I missed something.

Thanks!
