Yes, but there's no evidence angels can do that in the Dresdenverse.
Unless this scene
is that evidence. ;-) I note that bilocation appears MUCH more clearly -- in Christian tradition -- as something Saints do, moreso than angels. For whatever that is worth, since we're talking Dresdenverse rather than RW tradition.
I think we should take the phenomenon of "bilocation" as a given in the Dresdenverse: Jim has made it clear it's a VERY "kitchen sink" sort of 'verse.
Googling around -- not following the links just seeing what the results list on the first page looks like -- I see both arguments that angels can, and that they cannot, bilocate. Pretty clearly, it's whatever Jim wants, with adequate support either way.
