Where is the advance troop commnad?

[Bertoldo II]

I usually use advance command (F1 - F4) instead of charge (F1 - F3) to make my troop mantain the formation while approaching the enemy but in Bannerlord online this command is missing.
I'm not sure if before latest updated it was there or not or if it is not yet implemented

It's not implemented in the mod.
