Adding 4th axis

I have the dual endstop primo on the SKRPRO1.2 - I want to add the extra driver to control a 4th axis. I adjusted the Marlin config by enabling the extruder as this extra axis - however, after installing it on the board, the driver layout changed a bit. Originally the drivers are lined up like this: X1, Y1, Z, -, X2, Y2, - ; but after enabling the extruder, it took over E0 (which was X2 before) so the new layout is as follows: X1, Y1, Z, -, E, X2, Y2. It basically shifted the drivers one over.
Where exactly could I fix this in the config? Apart from this reshuffle, everything works great and I can rotate the 4th axis with G0 E123. Might just keep it this way if there’s no easy way to shuffle the drivers around. Cheers!
