Fuel line action groups

[xtoro]

I realize there is already a suggestion here for something like this, however, since necroposting is frowned upon, I'm starting a new thread.

I would like fuel lines to have actions groups to toggle the flow on or off, and maybe even reverse the flow.

Any chance of this happening? Maybe a mod request would be a better route to take? This would come in handy in a few designs of mine for reusable crafts.
