Sorting the formName by creating multiple forms isn’t always the use case. An example would be a single form that collections the same type of data (first name, last name email, etc, but needs to be sent to a specific email based on a location (like a franchise). Sorting without the aforementioned snippet means multiple forms that would have to dynamically appear based on the selected location.
Third party solutions are great, except they typically cost additional money.
The issue is that Webflow’s form system could be much better with a couple of small tweaks. Something like allowing a data field in the subject (formName.fieldName for example) would be a simple, but powerful addition.
