Tag multiple contacts for one note within 'Emails & Activities'

Within the ‘Emails and activities’ widget, it would be great to be able to tag multiple contacts within one ‘note.’ Otherwise, that effort has to be duplicated over and over.

So - if Jane and Jill are in a meeting, and we’re discussing Jane Inc., I would like to be able to go into Jane’s listing, make the notes about Jane Inc., and tag @Jill and have those notes go in to her ‘Emails and activities’ widget section as well.

Does that make sense? Multiple people, one note! Thanks!
