Posting Payments to Multiple GL Codes in X3

We are currently in the process of implementing X3 and are being told that we can only post miscellenous payments to one GL code through cash management.  If we want to post to multiple GL codes then we have to post to one via cash management and then do a secondary GL journal to distribute to the other GL codes.  This seems unbelievable clunky and time consuming.  Is there really no way to post it in one go?
