Show all activities in CTA Toggle at CTA Level

I’m not sure if this is the same as this post here: 

 or not, or this would be considered an enhancement to it.

I know we have this setting in Cockpit admin:

This essentially lets you turn the Timeline on CTA into the Company/Relationship level timeline. Wonderful.

The problem is that this is at the global level, and may not be particularly desirable by everyone.

I would like an easy filter/toggle at the CTA level somewhere here:

so that users can easily filter out noise if they just want to see records created on the CTA and/or Associated to the CTA from elsewhere.
