Sort Vehicles/Engines by Date

[Steambirds]

After deciding to go for a more modern approach and make a bunch of generic engines and tune them to the needs of my cars - I ended up having a lot of engines! Like, a lot! I think the ability to sort both vehicles and engines by date or capacity would be useful.
EDIT: I mean to select a date range, and only engines between that date will be shown

So a filter, basically - like how you can say, "Show only bodies from the last 10 years". That could be handy.

(Might also be good to have filtering by size - "show only engines that might fit" - when designing cars.)
