Is it possible to list out those other wait codes?

Yes and no...  The Storage I/O feature presents them as storage-wait vs non-storage-wait.  You will see the detailed wait types in the Trends section.  For example, in SQL Server, PAGEIOLATCH_XX and WRITELOG are the most common storage wait types.  However the Trends section doesn't group them by I/O and non-I/O.  The descriptions in the wait types will help you identify what is a storage wait.
