Option to limit overlapping time punches

[DouglasKreider]

Our company would like to use this product, but we are unable to find a way to keep multiple time punches by the same user from overlapping. As such, it is possible to have been clocked in, and get paid for, more hours than there are in a day. It would be nice if there was a setting to keep this from happening, or possibly a warning in the reports that something is wrong.
