Collecting alerts into one email from several panels

Hello,

In Grafa doc I cannot find information about could I collect alerts from a few panels into one emial notification. For example, I have two panels getting data from one table/storage and both of them have alert rules which can be triggered at the same time. And if this situation happens I want to collect these alerts into one notification and send by email. Can I do this?

Combining several panels into one with a difficult condition also did not give the expected result.

Thanks for help.
