Modify ios bundle identifier while building

Hello. My team is working on an ios game, and we have 4 devices to test, problem is: two of them are with provisioning profile - A, the other two are with provisioning profile - B(for somehow reason, we have to use these devices for this team), so two of them have to modify the identifier in unity or built xcode project to match their provisioning profile.

Is there any good way to avoid the manual setup and keep one-click build system?

Is there some event that will be triggerred before build?
