I love workarounds but actual LINKING or householding or connections works so much better so that we dont have a workaround. lastly, this doesnt appear to be important to the developers due to the fact that this was first discussed back in may of 2017. It would be great if this functionality was added. An easy way would to accomplish this would be to added a spouse field or family field then have the ability to search for others records. then they would be connected for both contacts.
