Is there a way to view all vehicles on any given mission in Great Battles?

[Blitzen]

So far I have only been able to view trucks , tanks & various pieces of artillery only if they are in action controlled I assume by AI.The stationary vehicles like those now around the airfields primarily don’t seem to be viewable by ant sort of keystroke or combination thereof.Is there something I have missed ? I have one other question regarding vehicles objects etc.: The number & types of viewable objects seems to increase and/or change as he mission unfolds.Is this a factor of timing?Distance? What? I haven’t really tested this in Tank Crew yet and in Flying Circus the number of vehicles , guns etc., still seems very limited, so I’m not sure if any of my observations apply to them as well?

I  think that unless the item is made a linked entry in the mission builder,   it's just like a tree.
