By default, Wasabi shows the Bitcoin Core smart fee estimate for transaction fees. However, in the settings, the user can toggle the option to [manually set a custom feerate](https://docs.wasabiwallet.io/FAQ/FAQ-UseWasabi.html#how-do-i-set-custom-fee-rate).
I am not sure if I understand it correctly, but I believe that the correct level for this in the score is `checkgoodfeecontrolfull`. If I am mistaken, then please disregard and close the PR. Thank You!
