custom logic for a logging activity - eg LogOnlyWhen()

[mo-rocks]

Apologies if this is already possible, but is there some way to specify when to log a field? I have a model with 2 fields that I watch, but only depending on a related item meeting a condition. Ideally, in the getActivityLogOptions(), I'd be able to use something like this:

->logOnly(['price']) ->logOnlyWhen(fn ($contentModel) => $contentModel->property === $desiredValue)

Is this already possible somehow?
