Naming items in PO Req

Naming items in PO Req

is there any way to have the same name but different part numbers. For instance I want to type HP Black Toner with a PN: C8767WN and the next item be HP Black Toner with PN: C9363QN etc....

but I get an error message. This would be the organized way to do this. or will I have to do something like have the PN in the name and also put the PN in the PN field. that would really make it look messy and unorganized.
