BPM: notify a favorite user

Hello, is it possible through sugarbpm to notify a user who has indicated a record as a favorite?

I'll explain better:

  • user 1 indicates the ABC account as a favorite
  • a note (or call or meeting) related to the ABC account is created
  • through BPM I would like to send an email to all users who have indicated the ABC account as a favorite

Thanks,

Mirco
