I have a client that will be using GravityForms to insert forms on a constant basis onto various new pages across their site. Problem is, every time they input a new form, the tab index is not created for that particular form and I need to edit their functions.php to fix this. Ultimately, they don't want to have to have me do this each time they create a new form. Is there a way to have this process more automatic, where a new form receives a new tab index automatically?
