Thank you. Click tags to select/unselect them and press Generate to build a dungeon with selected tags. The resulting dungeon may include other tags and some of selected tags may be missing, but overall it's pretty close to what you are asking about. There is no way to request a dungeon without a specific tag, but I'm planning to add a number of "opposite" tags to achieve the same effect (e.g. "single level" for existing "multi level").
