Ability to set step order when creating a workflow via REST API

When using the Create Workflow REST API endpoint to create a workflow, Step IDs are assigned to statuses incrementally but the ordering is not guaranteed. Step IDs don't have any impact on the behaviour of the workflow but the random order can make the workflow difficult to read in the UI.

It would be good to have the Step Order inferred from the list of Status IDs in the "statuses" property of the payload, or even to have an "ordinal which can be passed in with the statuses and transitions. Ideally the Transition flagged as "initial" would be the first step in the workflow and the rest inferred from the statuses array or with an "ordinal" property.
