Electrical - mechanical Maintenance order confusion

Dear Expert,

I have a query like we have different maintenance work center for electrical & mechanical and we have maintained mechanical MWC in equipment, now when order & notification will get generated it will copy mechanical work center and abviously the mechanical cost center against the same.

But electrical dptt. wants to issue something and cost incured should move to electrical cost center then if we select the equipment in the order ,, it will copy mechanical work center in the order, and cost will move to mechanical cost center, plz guide wat to do?

thanks
