So I've just found a way to do photo matching for TM. I'm on windows but the same method would probably work on Mac too with the right software. You will need 2 small apps: Glass2k and PowerToys. Glass2k can be found here- it is a small helper app that lets you make any window transparent. PowerToys can be found on the Microsoft store and is an app with multiple tools in one. The tool you will use inside the app is Always on Top.
So open the photo you are taking as a reference, make it transparent using glass2k (ctrl+shift+a number from 1-9) and then use powertoys always on top to pin it on top of all windows. You can then select your TM window and play with the angle of your camera until you find the right match.
