Flow colour gradients

Enable colour gradients from a flows source node to the target node like this example.

Is it possible to have a gradient set for the flow as an option next to the target and source?

I see above that there is an issue of whether the color is the source or the target, but a gradient would solve that issue entirely—because you'd have both, so it doesn't matter. I imagine this might be complicated on the back end, but I think it would be very beautiful and intuitive for users to have this feature. Here is an example I made in PS to illustrate my point.

From an understanding POV, this view helps us understand that money from one source turns into money from another source. Meaning, at no point is it really the source OR the target—it's both and that changes depending on the perspective.
