I made an account just to post this. I do not know if this is possible however it would be the ultimate addition to your already amazing mod. When in the VAB it would be great if you could select an itinerary e.g. kerbin -> duna -> Kerbin. Once the itinerary is selected there is a list of delta-v requirements that you can set for different stages e.g. stage 1 duna kerbin transfer, stage 2 low duna orbit to escape, stage 3 duna surface to low duna orbit etc. I am not sure how hard this would be to do however it would be such an amazing addition
