Offer the admin user a list of exiting segment names (i.e. combo box) when entering the Zapier segment. This will avoid the creation of duplicate segments with differing names and potentially reduce misspellings.
Please add a display of existing Zapier segments to admin users. This allows the admin user to construct matching segments within the adjoining marketing software. A higher goal here would be to create a view where we could analyze how our offerings have targeted market segments over time.
