List buttons customization

Hello! I need some help with the list buttons. When I try to assign an action to the button (open a form page), the action seem to be copied to all the bottons in the list. I need to assign a different page to every botton, how can I do this?

Hey !

Can you please share screenshots, showing where you are trying to map these buttons to custom URLs,
what you ask for is very common on should not experience any problems.
