BESR 8.5.3: Set/Configure priority for messages.

Is ther anyway to define/change priority for he messages generated by BESR?

I have selected the option to send email to administrator. I have selected high and medium prioroty messages (all : warnings/errors/information)
I am more interested in generating messages if the scheduled backup process could not complete or if the besr service was stopped/restarted due to any error. But i found that all these messages are generated in category "Information". The message about starting and comlpeting backup is 'High priority" while the message about "restarting service" is of "Medium priority", I want to set it otherway.
I have selected to create a new base backup at the end of every month, and keep last 2 set of recovery points. So the previous set of recovery poijts not needed  after that are deleted. But the message about deleting the unwanted old recovery point is also of "Information" type and of  "High priority" and create one message for each ending up in flooding the mailbox.
Is it possible to set/change priorities so that I can select bwhat messages I can receive?

Thanks
