Update existing activity should search more precise

We always use a View to build a list of Activities for a Contact - and then pass in contact id and activity id into the webform -> so that it just Updates that specific Activity:

Example URL:
/update-activity?cid1=4591&aid=20209&cid2=2&destination=/client-activities/4591
where cid1 is the contact id of the target, aid is the activity id, cid2 is the contact id of the logged in user (staff member), destination is the return value -> we want to return to the View after updating this specific activity.

I'd be tempted to remove "Update existing activity" -all together.
