You would need two different tanks to do that and they would have to have ball valves on them to let the air into the piston.

You would need a large air source tank and a smallish air chamber. A 3-way DCV or multiple ball valves would be needed to pilot it.

That's not a problem. That's a feature.

If you don't want to dump all the air, don't use a piston valve.

... or use a piston valve, but use a momentary pilot valve like a hammer valve.
