Change equip status of vehicle weapons from the vehicle sheet

Specs

Foundry 11, Build 315 SWADE 3.4.0

Description

Per the wiki article here, it sounds like it should be possible to mark Weapons as "equipped" for vehicles. However, I'm not seeing an option to do so:

Since I'm not able to "equip" them, none of these entries appear to be showing on the Weapons list on the Traits page of the vehicle sheet.

Is anyone else seeing this?
