Change event equivalent for custom fields (like ticket.groupChanged)

Hi Evereyone,

The Events method docs list Change events for default ticket fields — ticket.priorityChanged, ticket.statusChanged, ticket.groupChanged, ticket.agentChanged, ticket.typeChanged — which fire in real time as soon as the value changes on the UI.

Is there an equivalent Change event for custom fields? I couldn’t find one in the docs, and I want to detect the change live (not just on Update/Save via propertiesUpdated), similar to how ticket.groupChanged works for the default Group field.

Could you confirm if this is supported, planned, or if there’s a recommended workaround?

Thanks!
