FM seems not to support a swap of dUSDC for dETH, for example. I think this is not possible because there is not a pool for this pair.
However, the swap is still possible in 2 steps: dUSDC->CSPR, CSPR->dETH.
I would like to have this explicitly added to the swapping function, so that a user can enter both dUSDC and dETH, and that the swapper automatically determines the best execution path.
