Sort by configured options

[jonas-schulze]

What would you like to be added?

There should be a third sort order (next to "A -> Z" and "Z -> A") that becomes available if the selected field has predefined values configured.

Edge case: sort values not included in these options last.

Why is this needed?

I would like to sort the values of a field based on their predefined values ("Options" section in "Configure field" pop-up), for example by:

• Importance: Essential, Better, Best
• Size: XS, S, M, L, XL

Unfortunately, these are not the alphabetical orders, and I don't want to prefix numbers here.
