You mean you want two "sub tabs" for the "deconstruction" and "improvement" tabs then.
In the inventory/bank this is not standard and comes from an addon like AdvancedFilters.
But AF does not support the crafting stations.
Maybe you can use this addon to sort the stuff in the deconstruction and improvement tabs for you (no 2 tabs but a simple sort in your wished order):

Not sure though if it still works AND works at the crafting stations, so you need to test it.
