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

Even in Pro you can't do this exactly. You can't "paste" a copy to a different location and expect the resources in that second location to exactly match the original location. That's why you have to rely on the Fitter to place & route the post-synthesis version of the design in the destination project (we call it the "Consumer" project) into resources available at a different location (a forced location with Logic Lock or not).

If your concern is that this is a timing-critical block that you need multiple copies of, you may want to create specific SDC timing constraints for the block that get included with the sub-design. In the Pro edition, timing constraints can automatically be included with the exported .qdb file. In Standard, you'd have to manually recreate these constraints in the destination project.
