MobileClient: Filter for Tags - "no tag"

On desktop client, I have a search folder filtering emails without tag. Works great. In mobile client, I can only filter for individual tags, but not for “no tag”.

Am I missing something? Is this on the roadmap for the mobile client?

The mobile app is a beta app, made available for testing, but it is not yet complete.
