Right, there is no rank-based ordering for now.
IIUC this requires checking the type of the wrapped job and preparing configuration depending on this.
We could probably register some "rank-based ordering" factory by framework, and you could do the lookup here to construct the input.
However, this is substantially more work so I suggest it as a follow up.
