How do I perform a show detail segue without animation?

Question

I need a way to transition to a view controller which is embedded in a navigation controller from another view controller which is embedded in a different navigation controller without the second view becoming embedded in the first controller. I usually do this with a show detail segue however I need a way to do it without animation. I have tried creating a custom segue however I cannot find a way to set animation to false with a show detail segue.

Here is my attempt at making a custom segue. As you can see, there is no animation argument.

import UIKit


class PushNoAnimationSegue: UIStoryboardSegue {
    override func perform() {
        if let source = sourceViewController as? UIViewController, dest = destinationViewController as? UIViewController {
            source.navigationController?.showDetailViewController(dest, sender: nil)
        }
    }


}

I cannot use a push segue as specified in this proposed duplicate as I am moving to a different navigation controller containing a set of views and I don't want the views to become embedded in the original navigation controller as it messes with the navigation of the app.
