How can you use multiple instantiations of the same partition and synthesis qdb file?

It looks like if you delete all LL regions and just use partitions in projects, it will instantiate multiple copies of the same partition hierarchy. I guess your just not supposed to use LL regions anymore. Too bad, this used to be a very good tool and placed Quartus way ahead of Vivado. Now, I guess they are just about equal. Very disappointing. Hopefully they will fix this problem and get incremental compiling to be effective again and allow you to group functions in a given area to force the place and route to be faster and more effective.
