When a subcontractor is chosen and that Cost Centre/Load is referenced elsewhere (i.e. one order for multiple stages of work, or multiple activities), it would be good to have this labour allocation effected through to "linked" activities.
E.g. Lockup Carpenter - CC 500 Load 1.
Fix Carpenter - CC 500 Load 1 <-- Order Linked.
If a user updates the Lockup Carpenter, we could update the Fix Carpenter at the same time.
Dialog would read "Do you want to update other activities with a matching cost centre/load to also carry your nominated supplier?". A note would be added to each affected item, the same idea as the rescheduling tool.
