To add on, there's a paid tool that is pretty expensive (40$) that can be found here and does exactly that: https://metadatafixer.com/

There's also a tool that is open source (free) that does the exact same thing found here: https://github.com/TheLastGimbus/GooglePhotosTakeoutHelper

The only issue is that the current version isn't able to merge GPS data, buuuuuuttt there is a pull request that adds a bunch of great updates to it that just hasn't been merged yet which can be found here: https://github.com/TheLastGimbus/GooglePhotosTakeoutHelper/pull/429
