Yes! Sorry! (I was trying to save myself some typing on mobile by using X as a stand-in for Angel and for Rupert Giles, but that clearly didn’t work!)

“Angel Investigations” is an in-universe named organization with slightly fluctuating membership over the seasons, which is why I’m not sure it’s necessary to spell out all the members. But if you want to enumerate them for clarity’s sake, then I’m good with the Any: list in brackets if you are.
So yes:

Rupert Giles & Angel Investigations [Any: Angel Cordelia Gunn Wesley Fred Doyle Connor Lorne] (Buffyverse)

Angel & Angel Investigations [Any: Cordelia Gunn Wesley Fred Doyle Connor Lorne] (Buffyverse)

Thank you!
