I have a form called Nueva venta (New sale) where I enter data such as customer details, products purchased and form - amount of payments. However, payment details are not necessarily entered at the time of the sale for some customers that get credit.

So I created a custom action button called add payment so when I click that, I get a pop up with the form pre-populated to edit the record and I'm hiding almost all fields except the ones relevant to payment form. Is there a way to hide or change the form Title when accessing it on a pop up?
