Right now you can emulate this by putting your other instance links in your bio. I do think there should be a dedicated "linked instances" section which is more coordinated (only lets you link when you can access both accounts, and updates every other instance when you add a new one).
I hope they add this feature soon enough. The nice thing is that anyone can add this feature, and if the devs approve it, most active instances will likely update. I won't be the one to though :)
