Is there an efficient way to merge seperate "Favorites lists" to make a growing master list which would be exclusive to a client for reporting purposes?
I want to take another searched list; reduce by marking certain contacts; and then add to a favorites list as well as take two seperate favorites list used in the past and merge them into a master list.

Generally,

If your trying to update favourite lists all the time your not making best use of the system. Try using a UDF for regularly changing lists and lists you need to regularly combine.

Convert your favourite lists to UDF lists with Global edit. Try one or more table UDFs
