[Question] Can validation only be performed when submit button is clicked?

[KenBrannigan]

Is it possible through some settings to only have validation fire when the submit button is clicked? Currently, this happens before the first form submit but if the first form submit fails validation then modifying the failed field will fire off its validation onblur. I would like to suppress this onblur validation and only revalidate the form when submit is clicked again.

If this is not currently possible is it a feature that can easily be added?
