Additional Template Logic Available

In my form, I have a multi-select dropdown and based on whether the requester has "included" one of the selections or not included that selection, determines whether one field should be showing next or another field should be showing next.

Specifically, the user should be able to select from a series of options on the type of service they are requiring, but can also select "other" as an option, If they include other in the selection, then a text field will show asking for a description for the services required.

However, presently, while there is logic available to look for whether the selections included "other", for the oposite scenario, suggesting that the user did not include other in their selection, the closest available choice is "not equal to", which then only looks at whether the values were not an exact match.

I'd like to see a selection available for "not any of" or "does not include"
