Forum:Gernade switching?

Ok lastnight I was in the arid hills pwning low lvl skags for shits and giggles.I had two gernade mods a crossive rain and shock bounceing betty there were a lot of skags rounded "skag farm" up so i could kill them all at once i wanted to shock them at the edge and dissolve them in the middle so i through the shock BB and then right after i switch to the rain and through it. and to my surprise the shock BB turned into crossive BB and crossive rain. I went and loaded up on every mod I could find which was not that many cuz I was tired i found that if u through any kind of BB gernade and then equip a contact or rain gernade right after it it explodes in to that kind of elemental effect so im wondering if you can do this with transfusion gernades i would not mind a crossive transfusion Would you? I dont know if this has already been found and im just a newfag for not looking sry in advance if it has. P.S. only works in single player.
