Sub-Items integration with automated emails

Hi everyone ,
We use automaticly generated email each day at a specific hour and it realy works great !
I could realy use the sub item to help on certain board that need multiple info on the same project.
but all info within those sub items cant be sent by mail …
i dont want to miror those on my main line ( less colums is better )
The fact that i cant generate an email including pulse data from the sub items keeps me from using them.

thank you
