Su-25T weapon loadout

[Razor5-1]

Hi,

I am trying to add bombs to my payload. However I am only able to add one bomb onto a pylon, I know the su-25 can carry multiple bombs on one rack. Can somebody please help with this issue of putting multiple bombs on one rack like so..

in russian loadouts you can load 2 FAb-250 or 4 FAB-100 on one rack. It is listed as a type of bomb. I forgot the exact name of the rack
