Currently, it is not possible to clear an Epic's Initiative using automation rules. The automation rule only allows selecting a different Initiative (Screenshot 1)
Inconsistent with Feature automation rules which do allow the Initiative to be cleared (Screenshot 2)
Add support for clearing the Initiative on an Epic, similar to how this is supported for Features.
Because we've disabled the ability to delete epics, features, etc., epics and features that would have previously been deleted are now assigned to a special Parking Lot "Trashbin" release. We would like to automate clearing the goals and initiatives associated with the epics and features that are assigned to the "Trashbin". Today, we can do this for features but not for epics.
