Jet & Heli Test Range

Just like the shooting range, I really wish there was an easy offline practice mode even against bots for vehicles like Jet's & Heli's. I know the current work around is finding a custom portal or creating your own but I've actually found I can't get it to work properly at all. This wouldn't be such an issue if it was just a default mode. That's my suggestion :)

Also, would love to see in the future an official mode that was Jet's only which I think existed in BF4. 
The aviation is too cool in this game to only be experienced in such small amounts.
