That quote in that post is 14 months back I believe, what I think you are asking is whether it is possible to put expanded details about whether the UPS service is "priority mail" "express" or whatever in the detail, invoice and packing slip pages.

I'm suprised that it doesn't give those details on any installation (I'm UK based so don't use those services), if this is what you are asking it's going to take some editing of several pages.
