Adjust/Add to Firearms List Sorting

Matthew Oakey,
When in the Main viewing portal, where on the left lives a list of firearms.
Above that list is a drop-down menu to choose which group of firearms to show in the List.
The automatic DEFAULT order is "Alphabetic" except when choosing the "Custom Catalog #"
My request is three-fold in a sense... I would love, as I am sure that many others would, when I choose "In Stock" that it would list those in "Custom Catalog #" order - that is "Numeric" order.
Secondly, that drop-down list is kinda sparce as far as how someone might like to view, in an order, their stuff. So I wonder how hard would it be to provide a way for a user to create a custom "Order" to be used in that list ??

Finally, building on the first thought above, as far as it goes, the ability to choose between "Alpha" or "Numeric" order for viewing,

a third option should/could be by "Date Purchased" for those"In Stock" and "Date Sold" for those either "Sold" or "Stolen"

If you could get this done by Summer - THAT would be an awesome task, and If I can assist in some way, PLEASE don't hesitate to ask !! If I need to send some Beer, Wine or Snacks money to expedite - well that's alright too !!!
