Edit the subject of a logged call

Edit the subject of a logged call

Is it possible to edit the subject-line of a logged call? Users have the tendency to ask multiple questions per e-mail of which only one applies to the IT department and then we receive a call labeled "Fwd: Re: Re: Library Talk" but the IT-question is password related.
Or a call-subject is "Re: Password" but now the question has changed to software purchases etc.

It would be convenient to change or edit the subject so that it is easier for an IT technician to pick up a call (an not assume it is password related when it is about something else).

We are currently on 8.0.0 Build 8016.
