Close Preview After Copy/Save/Upload

As heavy duty user who makes multiple screenshots per day using Capture, it would be very helpful to get a setting in which we can indicate that the preview should close after copying, saving or uploading it. The problem that currently occurs is that after copying (or saving) we go to our email or Word and we continue in there. We forget to close the preview in Capture and later on, when we try to make a new screenshot, Capture doesn't respond because the old preview is still open. In our case we would prefer the preview to close automatically after we clicked the copy, save or upload button.
