Idea Summary
When you have a modal page, you may “Always” need a button to cancel the modal page. so for that we usually create a button Called “CLOSE” or similar, then in the builder, we need to associate a dynamic action instead of submit, and this dynamic action needs an action close dialog.
The idea is to remove this dynamic action and action, and just add a new option in the button properties behavior > action: add a new one called “Close Modal” or similar, this will close/cancel the modal, the same logic that we usually do for CLOSE modal.

Use Case
This is always used when we create a modal, and will reduce time creating dynamic actions.
This also could be a default action when we create a page from the wizard and the wizard automatically currently creates a dynamic action and action for close modal.
Preferred Solution (Optional)
Just add a new Option in the list of actions of a button.
