Every stage grouped by operator. Drag a card to reassign it — including
locked stages (still waiting on an earlier step), so the
workflow can be planned ahead.
Bulk assign steps
Tick a step to change it. Every non-complete step with that name — across all elevations
of this work order — is set to the operator(s) you pick. Select more than one to have
them share the step (it shows in each queue; whoever completes it clears it for all).
