Indicating a record type as a condition for smart folder membership

Is there a way for me to indicate that I want a smart folder to have all emails as one of the conditions? I want to have an easy way to look at all emails that have a particular tag. The thing is, there might be other records with the same tag, and I would not want them in that particular smart folder.

Thank you very much!

Yes, you could make a smart folder like this.
