Ability to modify CSM sentiment within the timeline

It would be great if CSMs could update the sentiment scores (or even other custom manual scores) via the timeline.

Use case:

As a CSM, I have a meeting with X account.  I have a feeling about how things are going and want to update the sentiment in one place.

Current workaround:

We have a drop down menu added to our timeline and a rule that gathers timeline entries, analyzed the sentiment score and updates it.
