To Devs quesiton about docking module

[Ponge]

So the Civ. Carrier has 3 slots that i presume are normal docking module slots and then 2 heavy ones.....
Are those 2 heavy ones for a Heavy Docking Module that can be made on a PoB or are they the same as the others but in that slot it makes it carry larger ships.....?

The heavy are basically just docking bay slots that can dock SHF's and Freighters, they just mount the normal docking bay

And are these heavy slots working yet? So if I mount a docking module to the heavy slot, I can dock a freighter, or it is not implemented yet?
