CURRENT_USER for the "Update an issue field" where the field is "People"

For the "Assign an issue to someone" rule "someone" can be the active user.

For the "Update an issue field" where the field is "People", e.g. "IDC Responsible", there is no selection to set the person to be the active user or reporter, only a specific user?

It would be useful to have the same options for a updating a People-field as in the "Assign an issue to someone" rule.
