Kentico Admin - Re-arrange Order of checkboxes

Question

For my Articles page type, I have an Author field that displays a list of Employees as checkboxes in alpha order based on their names. The thing is for articles, the authors are listed based on their contribution level (not their names).

Example: in admin - the checkboxes are listed in alpha like this: Bill | Fill | Jill | Will.

On the article webpage - the author can be in any order such as: Will, Jill, Bill

How should I go about doing that? I was thinking about creating multiple Author fields (Author1, Author2, Author3 etc), but that's cumbersome.

Is there a way to make the checkboxes draggable so that we can move checkboxes arround & re-arrange for each individual article, if needed. If that can't be done, what's your suggestion to go about doing this. Thanks for your input!

I would suggest to convert your authors into pages (e.g. content only) and then use Pages field on your Article page type that allows you to order your authors (using arrows).
