Thank you for the explanation Peg, I understand where you’re coming from here.
Can I ask if my explanation of a new feature on the attached thread, is along the lines of what you’re looking for?
From what I understand, you have the same email attached to every item and as such all emails are pulled into each item:
The filter I am referencing in the above thread allows users to filter threads specific to that item only. Meaning, if I have two items with the same email in the email column, using the “sent from this item” filter, I would be able to filter conversations that belong only to that item. That being said in order for this to work, you must respond to or initiate an email from within emails and activities.
Let me know!
