If you are looking to allow access to all users to this same list, one way to do this is to go to Call Routing/Translation Pattern. Here you can use a "dummy" code to build a list of numbers, that can be separately published to all.
ie #50001, #50002, #50003 etc
We have multiple large locations accessing this in our system, so location A would have #50001 to #50999, location B would be #51001 to #51999 etc. Translation pattern, Partition, calling search space and Called Party Transformation Mask are the essentials here.
Translation patern would be the dial format from above you decide on (#50001), and Mask would be the number as you dial it from your phone.
Hope this helps.
