Best way to copy data to avoid user overhead

Summary:

Currently copying data using business rules which are attached with screens. Business rule is executed while pressing Data Save button.

It takes little longer to run the business rule during Save as screen has large data.

1. Is there any way to saparately execute business rule with one/fewer clicks . (Business user would use it so looking for most simpler approach)Would like to avoid Data Copy option from screen, as user needs to set dimentions and other details
2. Is there any way to execute business rule during Submit button of smart view (Would like to execute rule during save similar to screen)
