Smugmug allows you to create sub-categories and create multiple galleries within each sub-category.  Gallery names can be the same across sub-categories yet are maintained as separate galleries.  Example: Create East and West as categories and then SE and NE within East and NW and SW within West.  I can then place a "Family" gallery in each of the 4 sub-categories.  When trying to upload to Smugmug from PM the PM uploader does not show the sub-categories (in this case the selections would just be Family, Family(1), etc.).   The LightRoom plug-in for smugmug is really good and something to check out.
