It would be great to:
1.) Have an ‘add/remove’ association action in a workflow
2.) Be able to add or remove associations in a contact/company list view
Great idea! We need this.
Urgent! I vote for this feature.
Agreed, upvote!
Is this a thing yet? It needs to be!
This would be extremely helpful.
How does it not exist??
Yes!!!
Yes please! Much needed
Much needed!
I want this as well. And I want it with possibilities to add criteria’s to it. For example: remove all associated contacts that has X (another business unit/property), but not Y property.
So much needed.
I need this asap. Such a struggle without it - sometimes companies have an incorrect domain, and I now have hundreds of contacts that I need to manually remove and re-associate to the correct company record. 
Must have feature
Must have feature. I am trying to create an internal form that will allow the submission which creates an object to be associated with the employee who has submitted the form, as well as the company they have specified the form submission pertains to. Even though we have gotten this to work, the form submission causes my employee to be associated with the company for whom the form was for as an associated company. Being able to have a workflow to disassociate objects is key for us to use this process while not creating associations for internal employees to other companies.
Yes please! I especially want to be able to set rules in a workflow that can auto-remove association if certain criteria are met
This is a must.
This is definitely something that would be very useful.
yes please.
I strongly hope that it will be implemented from Japan.
