Ability to Block Time in a slot that had a patient cancel

Currently in InsightGo you are unable to put in a "meeting block" in a slot that once had a patient that has canceled or no-showed. In order to block that time for a meeting, the canceled patient needs to be deleted from the schedule, which makes it hard to keep track of canceled visits. I would like to be able to add a meeting block, without deleting a canceled visit just like you can in the InsightEMR.
