Custom getter in observable property when using partial identifier

[sensslen]

I'm converting a legacy codebase to communitytoolkit and am currently facing a few instances where the getter of a proeprty I seek to replace has custom logic (e.g. a fallback value in case the backing field is an empty string). The generated code fia a partial property is get => field; would it be possible to define the getter in the user code instead?
