I would like to see the addition of a taxonomies system (an idea I got from a CMS called Orchard Core, I'll refrain from linking to the docs as it's a super simple concept and their docs make it look more complicated).
Provide the ability to add tags to an entity (stations, fleets, ships, etc). Could be a csv string, space-separated string, or a string array, just needs to be tokenizable, most OOB search packages probably work best with a single string data type instead of an array.
Then there would be a search page added to the player property tabs. You could favorite a few tags or tag combinations for convenience.
Now you have a dedicated field for player categorization and you don't have to fudge the entity names to get usable sorting.
You could even have tags attached to ship presets and station templates so they come along for the ride when building.
Here are some simple mock-ups of what I have in mind:
