Quartus: Calling a sub circuit twice. How to use exact same post-fit placement and route

Hi everybody,

I have a big circuit A that calls sub circuit B twice in its design. Let say sub circuit B is developed, compiled, placed and routed by another person. In A, I want to have 2 design partitions that have exactly the same post-fit placement and route that the other person gave me. Is there anyway to do that in Quartus?

Thank you so much and happy holiday!
