Filter without dot in name

Hi, is there a way to add a smart filter that will display all the glyphs that DON’T have a period or underscore in their names?
For example. Show: A B odieresis six
Don’t show: parenright.loclIWR j.alt f_a

In the filter dialog, press the plus button on the right while holding the option button. That will give you a compound rule where you can negate all following rules.
