Multiple image targets for one object content

In AR technology, how to have multiple image targets to render only one object? (not multiple targets for multiple objects or one target for multiple objects)

Hello there, I'm working on a AR Marker-based Indoor Navigation App. In order to render/Augment a navigation path on user's screen, I started with creating a path(cuboid) object when a single image target is scanned, but once the image target is lost, the path starts flickering. To avoid that, I want to know how to have multiple image targets to render the same path object at the same position in the space where it was initialized so that I can see the whole object right from the start to end just by walking through it.

In the attached image, how to add multiple image targets at every corner to show the same path object through that corner.
