Just to add on, this feature will be useful in cases where different groups(labels) of companies/contacts need to be sorted to different teammates. It would help if there was a Workflow - If/Then filter that sorts companies/contacts by their association label and sets ownership to a teammate accordingly.
Yes, please add a filtering feature! We have two different types of contacts in our DB. One type typically is only associated with one deal. But the other type is typically associated with many deals. When we associate the second type with a deal, ALL his/her activity from ALL the other associated activity gets associated with every deal. Makes the Association label not really work for our use case.
