Accurate time stamping of logged emails

Currently, HubSpot only offers the ability to manually log emails in 15-minute intervals. This makes it impossible to accurately log a set of emails that have quick replies.

Could you implement a way of manually logging emails with 1-minute intervals, as they currently are with automatically logged emails?

Thanks!!

+1 It would be great if any time could be selected for logging emails to increase the accuracy of the logged emails.
