Is your feature request related to a problem? Please describe.

There currently is nothing in place to filter these values:

Describe the solution you'd like

E.g. or something.
Something along these lines:

Describe alternatives you've considered
I have considered creating a template for this myself, but I think more people can benefit from this feature.
