I wasn't able to find the correct Product and Category to log feedback about Sales CoPilot, so logging against D365 Sales General.

Using Sales CoPilot, I'd like the ability to customise the form and fields specifically for the Appointment entity with a custom field that we have added, which works fine using the Dynamics 365 user interface, but not when using the Sales CoPilot interface in Outlook or Teams.

More generally I think this should be applicable to other Activity based entities as well.
