Shortcut for custom sorting order

[Speaker4thaDead]

Hello, I'm trying to make a custom/virtual tag to use to sort my music, but I'm not sure how to do what I want.  My goal is to make the equivalent of this custom sort:

But I don't know how to/if I can get the year to sort descending instead of ascending, while still having the artist ascending alphabetically.  Right now I have this:

If there is a better way to do this I'm all ears.  I switch between different sort orders (artist, rating, year, etc) all the time but by default I like to use my own custom order, but it's a pain to navigate through 2 context menus every time as shown here:

I used to use a hotkey to get to the sorting menu quickly, but that field has since been removed from possible hotkeys.

Use a virtual field with the following formula for the sorting purpose only:

$Sort(<Album Artist>)$Replace($Replace($Replace($Replace($Replace($Replace($Replace($Replace($Replace($Replace(<Year (yyyy)>,0,j),1,i),2,h),3,g),4,f),5,e),6,d),7,c),8,b),9,a)<Album>

Perfect, replaces the years with letters in the opposite alphabetical order, thanks a lot!
