Download to Mulitiple CSVs based on field value

I searched the board and didn't see anything that fell into this category so here is what I am trying to do.....

I have a table that gets wiped out and then repopulated once a month by a .csv upload.  One field in that table is called "Category".  The number of distinct values in the "Category" field can vary between each upload, depending on that particular data set.  One month, I may have distinct values of:  'Cat 1', 'Cat 2', 'Cat 3'.  The next month, it may go all the way up to 'Cat 10'. 

Each month, I also want to generate .csv downloads for all records in each distinct "Category" value. 

If the number of distinct "Category" values was the same each month, I could hard code a pipeline to do this.  But since the number of distinct values varies each month, I am unsure how to make this happen within Quickbase.

Any suggestions will be appreciated.
