How to link a look up table to a pick list

I have a document in which one of the strings is of the type “Pick List”. I have added the different choices for the sting in the “Pick List Choices”.
Is there a way by which i can link the choices to a look up table, so that everytime i want to define a new value for the string, i would add it to the lookup table and it would reflect whereever i use that document.
I hope i make my problem clear. Please let me know in case it is not.


You could map the string list directly to a string table variable and then call pub.string:lookupTable service.
