Bulk Update of Validation

Hi,

There is a built in validation that is currently being used by multiple fields in multiple Request Types.

Since we can't modify a built in validation, I am thinking of making a copy of that validation and do the modification I needed.

But the next question would be how could I bulk update the existing validation with the new validation?

Is there a way to easily update all the fields validation in bulk instead of one by one changing it?

Appreciate your response and help on this. Thank you.
