Maintain Linked Items When One Item Is Archived

We use the linked item and mirror column features a LOT. Our boards also get fairly bloated. Especially with things like our email creation workflow process. So, to keep things clean, I would love to archive items.

However, I cannot do that without losing the link and the data in the mirror columns. So, if we need to go back to those emails, then we will have a lot of missing holes.
