Drop Tank Partly Empty?

Hi guys, I want to create a mission with warbirds air-starting as if they had already flow for some time. They should be carrying drop tanks which are perhaps only 1/4 full.

However, if I add a drop tank to an a/c it is always completely full, and I can only reduce the internal fuel in the ME.

Is there any way to start a/c with only partly filled drop tanks?

Not that it helps, but I have the exact same question.

Just in case anyone find this threads, here is what I found out.

Currently there is no way to load a "dry" external tank. Most AC however will siphon the tank into the internals. For a mission I built with the F-5, you start with approximately 25% internal fuel. Over the course of the next 5 mins or so the externals are siphoned into the internals, filling them up. I'd recommend checking this occurs with the AC you have in mind for this.

So if you don't need the player to roll into action the second the scenario starts, you can effectively cause the same results in a few minutes of flight time.

Most modules (e.g. MiG-21) will immediately (0 seconds) transfer any external fuel to internal on initialization. So setting internal fuel less than full will cause internal tanks to fill as much as possible given total fuel and remainder will be in external tanks.

Exception should be Mirage 2000 which used to do above behavior but is moving to not doing this instant transfer on initialization. I don't know how it is at the exact moment.

I was actually thinking about the P-51 and Spitfire. Neither of those have any connection between drop tanks and internal tanks, but I suppose it would be worth a try to see if this is simply some kind of mechanism DCS uses to do this.
