[2003] Excel+VBA: SaveCopyAs with password support?

Is there any way to use the SaveCopyAs function but with password support?

I need to keep the template excel doc in-tact and unchanged. So I'm using SaveCopyAs and saving the updated version of the template xls doc to aonther location. But, when it's saved to that location I want to password protect it. Not sure of another way to do this without using SaveCopyAs, but I can't figure out a way to password protect with that function call.
