I would like to edit an expense that has an unsubscribed / permanently deleted user in it who has since been removed from the group. I can not edit the transaction since they are no longer in the group, and I can not add them back to the group because their account is deleted. If I remembered their original email, I could actually add them back, but I don't and I can't see what the original email address was anywhere else in the UI even though the name shows up everywhere in old transactions.
