You can do it using Quartus Backannotate feature.

First compile your design (synthesis + fit).

Save the project. Quartus will add all nodes of your design along with their locations: LABs, FFs, PLLs, Transceivers.

Find the node you're interested in, and changed to the desired location. Remove the rest of the backannotated constraints.

Thanks,
