There is only one way: XREF
but please not in Paperspace, that works, isn't a good style.
Or is that only for Layout like a legend? Thats ok, place XRef in Layout directly.
Workaround if you dont like the XRef-Display on the "correct" Place " in Modelspace:
Place it on extra Layer at 1000,0 for example, copy your Viewport,
go into Viewport and change view with command "-PAN" to move 1000,0
freeze all other Layers.
