Feature Request: Add ability to manage Entry and Category sources outside of the field itself

[jsunsawyer]

It's difficult keeping LinkIt field source options in sync with each other with several LinkIt fields used throughout various Super Tables and Matrix fields. If a new entries section gets added and you want users to be able to link to it, you have to edit every single LinkIt field's options.

Having the ability to create source groups and manage through a settings panel would be super helpful.

Nice idea, will see what we can do to improve this.

This should be covered by the preset fields feature that we are looking to migrate over from our Colorit plugin.
