I need to trigger on "all form submissions EXCEPT Form3 and Form7"

If I have 10 Forms, I need to filter the workflow trigger "form is in 1, 2, 4, 5, 6, 8, 9, 10" (and remember to add 11, 12, etc. in the future if I ever add a new form.

Instead, I just want to filter the workflow trigger for "form NOT in 3, 7" (such as internal forms like when staff enters a new Trade Show contact)
