Hello Kris,
I have reviewed this in my test org as well and it looks like this is the only option, since its a newer feature as of Oct 2024 I recommend submitting an enhancement request. I double checked the ideas lab for better sorting for parked emails and came up short.
There maybe also something in the appfoundry made from a partner that helps manage parked emails.
Cheers,
