Please update the Workflow field to include the ‘Center on a Date Property’ on non-Contact Workflows, specifically Company and Deal fields at the very least.
Since the function is focused on the property rather than the field itself, and attaching emails to certain contacts is also based upon a property rather than the Contact field itself, and also considering that delay timeframes are available for delaying when a process is triggered going To a date, I see no reason why this From date centric function cannot be implemented to the Company or Deal fields. This would surely fix a lot of problems for a multitude of workers who focus their notifications on these other fields.
