The logistics requests for the player, and vehicles, are in the same set of logistic groups as for chest. Constant combinators also are included in the access list.
The first thing with a logistic group name in the game will 'set' the values for that grouping. Even if it's a ghost. You can make a blueprint of a constant combinator with the logistics groups defined in it. Place that blueprint, even as the first act after the opening cut scene, and those groups are defined for that save. Open the character's logistics requests and pick the group you want, and instant setup. Same for tank/spider etc.
