Acitivity Feed

Hi,

In the main form of the account entity, i have a section called Notes and Activities which include three tabs: Posts, Activities and Notes.  We are noticing that when we are tracking an email to a specific account via outlook,  the new activity is also showing up under a different account where the contact of those accounts is the same. 

Is there a way to edit the Activities section to filter out those records not directly link to that account?
