How can I get a checklist I already have on a card into alphabetical order?

[Marion Lowrence]

I am having to trail through a long list and adding things that are already there as missing them - can you put in alphabetical after you have created a list?

Perhaps you want to find a solution that avoids duplicates instead.

I did a proof of concept for a client to create a checklist for all attachments in a card and to remove checklist items that does not match the attachment list names. There checking for duplicates is definitely possible. This is for work as it progresses through different stages of production (list). 

It does not use Butler or any power-up so that may not be what you are looking for.
