Hey I would love to be able to go back into a call once I have saved it and create a task connected to that call. Sometimes I really need to reflect and think about what is the next step before creating a task. Either that or be able to create a task and have it assocaite with a call or email within that contact. This would be a time saver as well because currently and create the task and have to put in notes to check back and review this communication (call or email) in my notes on the task if the first option was available the reference would be there and I would save time not having to make the reference and be able to view the reference when I go to complete the task. I will say that HubSpot has made me a very task oriented worker bee.
This would be a very important feature for us to have to be able to assign an action to our service team and then have the record back to the initial call or email. It would also be good to add comments to emails similar to what can be done for other activities.
