Pausing Material Input - Ore Sorting.

The nice new larger sortation plant... It's a gripe that potentially has a simple fix. As it stands now it can be bottle necked by a single resource as it cannot output it. As it now has the potential to output 10 different resources, in addition to the current bin icon to completely remove the offending item blocking the machine, can we get a pause icon, to pause trucks bringing just that specific resource to that machine. So then we either get truck has no available sortation or it goes to one that is available to take said resource..
Food for thought..
