Use 'user id' as a field that can be excluded in Advance Searches

Currently if I want to run an advanced search to create a mailing segment for a particular membership level I have to use the field 'name' to create a criteria of 'is not' when building the search. This removes the members with the name(s) specified as you can insert and define the criteria multiple times.

However, less prone to manual error would be the ability to insert the 'User ID' as a criteria and then have the option to specify 'is not' in the advanced search and then paste in the relevant member/members' user ids. This isn't available as an option - the field for user id only allows you to specify 'is' or 'contains'.
