A customer should be able to test a check before hitting the create button in "New Check" wizard. The check will instantly run and present the results before actually creating the check. By doing this, the customer makes sure the check is running or if the customer needs to make changes to the check configurations. This also helps with the SLA of the check, instead of the check failing few first runs and then re-configuring the check, which impacts the SLA of the check.
This is a great idea. I´ll promote it to a feature. I can not give a more detailed plan than that though.
