How do I add multidimensional concave?

Im trying to design a longboard that has concave in many directions. For example i want radial concave down the board but i want it to become flat for the tail. Simultaneously i want the side profile to have different concaves for wheel wells and the kick tail. I have figured out how to do each individually but I cannot combine the two.

This is tricky to do until Onshape implements 3D sketches so that we can lay out the boundaries of surfaces in advance, and use them as guide curves for lofts, which can then be knitted together to form a watertight solid.
There are workarounds, involving extruding orthogonal surfaces for the sole purpose of using them in construction, and trimming them with other surfaces so the resulting edge is a 3D curve .... but they are fairly labour intensive.5
