Custom report wildcard support needed

Custom report wildcard support needed

The Custom Reports are a step in the right direction. However, support of wildcards is needed. For example, if I want to create a report that shows me all Remote Interactive logons but I want to create a filter that says not to include account names that begin with a certain string, currently I can't do this -- all accounts to be excluded have to be selected using checkboxes and new accounts matching my criteria are not added to the filter. When will this functionality be included?
