Hi Alex,
First off, you should not set up "holds" for something like this. A Hold is only supposed to be temporary, for some legal incident, relevant for only a short period of time.
What you are trying to accomplish is part of Default and Custom Retention rules, which are supposed to be permanent.
Default Retention is used to set up a basic fail-safe for accidental deletions, where Custom Retention is where you really decide how long user content should be available, even after voluntary deletion.
