Unfortunately, Apple doesn't currently offer a direct way to transfer game progress between accounts.
However, there are a few potential workarounds you could consider. Firstly, some games offer their own account systems or cloud save functionality independent of Game Center. Check if Sneaky Sasquatch, or any other games your daughter plays, offers such a feature. If it does, she may be able to create her own account within the game and transfer her progress that way.
Another option is to continue using your Apple ID for game progress on her device, but ensure she has her own Apple ID for other purposes. While this isn't an ideal solution, it would allow her to continue playing her games without losing progress.
Lastly, you can provide feedback directly to Apple about your experience and request a feature to transfer game progress between Apple IDs. Apple often listens to user feedback and may consider implementing such a feature in future updates to Game Center or other services.
In the meantime, I recommend exploring the options within individual games and considering which approach works best for your situation.
