Is there anyway to search for OmniVehicles that I'm missing? There's a OmniMech and OmniFighter under the subtypes, but not for vehicles?
Excellent question! The short answer is not in the way you want to
Longer answer: Each unit has a type and a subtype in the database. For mechs and aerofighters, it’s a binary proposition - it’s either BattleMech or OmniMech in the case of mechs, for example.
Vehicles use the subtype to show their movement mode, be it tracked, hover, wheeled, VTOL, etc. In order to make omnivees searchable, you’d have to add Omnivehicle - Tracked and so on. So to search for all omnivees you’d have to select all of them from the subtype submenu. Cumbersome, though not completely awful. We briefly discussed the option months ago but didn’t make any decisions.
In this case, the workaround might actually be better. Each omni unit has a config called <Base> that represents the unit as a whole regardless of config (it saves a LOT of space on internal production notes). Under the units tab, if you set the unit type to combat vehicle (and / or support vee) and Base> in the unit name text box, it will show you all of the chassis that are omnivees (don’t use <base> or <base because the MUL will think you’re trying to inject code and freak out)
