AND/OR/NOT in filters for custom text fields

I am using custom text fields in some of my Wrike projects. I can filter using the custom field options "Contains", "Starts with" etc, but often I want to filter for more than one thing in that custom field. For example I might want a search like "Contains x AND Contains y". This could work either by being able to use Boolean operators in the filter field like this:. Or it could work by having the option to have multiple filter fields under the custom field. Either would be great.
