Problem is that you have to activate this process somehow. You can use cronjobs but not every provider supports this feature. You can add this to a script which is called by a participant several times a day. But you also have to store the information when the emails were sent to not send them again.
Of course you can
add this as a feature request to the bugtracker. Please describe your problem/solution as detailed as possible. But don't be angry if we consider this problematic. A donation would speed up the implementation of this feature
