It is common for WeakAuras to have Option Group arrays with very large lists, here's an example from the popular WeakAura "Spell Cooldowns on Nameplates"

Trying to find the entry in these lists can become tedious when there are a significant number of entries. An option to sort the entries by entry name alphanumerically would be very helpful.

Describe the solution you'd like
Add an option under Entry Name Source to sort the entries alphanumerically by this value
