Microsoft Project Enterprise Edition

Can i assign more than one coding to an activity in MSP, to enable me to view a filtered view for more than one field that the activity may fall under.

For example if i were to code an MCC installation as "Electrical works", would i be able to create another code library and assign a code to that same activity to filter all works for "Smiths Electrical" to see a filtered view of all the works done by Smiths?

Thanks in advance,
