[[1.9-1.10] Configurable Containers]

This may have been asked before but; Is there any way to automatically configure the fuels inside a tank to an engine? I find it quite difficult to fine tune fuel amounts for an engine that uses 2 non standard fuels, or uses them in different amounts to normal LF/OX. Something similar to RealFuels system where you can automatically fill tanks with the correct fuel mixture for the engine attached to it. This might already be a feature that I'm just missing but It would be awesome to have if it isn't.

Am also having issues in 1.12.3,  The best alternative I've found is a mod called Configurable Containers. But I have difficulty putting the right ratios of fuel into the tanks, something this mod does very well. B9Partswitch also works with some tanks but not all of them for some reason
