Attribute Limit Of 5000 When Mining A Cube

I'm trying to build a association model in the Standard Edition based on an existing cube. I keep getting the error:

Error (Data mining): The 'Product Recommendations' mining model has 60385 attributes. This number of attributes exceeds the attribute limit of 5000 allowed by the current version of the algorithm associated with the mining model.

I created Cube Slice filters and those limit the Customer and Product dimensions (Product is Nested) to well under 5000. The error message also does not change. The number of attributes is equal to the number of rows in the Product dimension, but I expected the cube slice to reduce the number. I tested all the SQL used while it processes and with the MDXFilters the number of rows returned is well under 5000.

So, in short, the final questions is, is it possible to create a mining model in standard edition based on an existing cube where the nested dimension in the model has more than 5000 rows? Is there some other way to filter the query?

I guess my only choice on this if there isn't a way is to extract the data into relational table with only the rows I want to analyze....that's a huge pain and doesn't really make sense when the filters should limit the model size.

What is annoying on this is I can't find one reference anywhere on the microsoft site that this limit even exists within the product...

Thanks for any assistance on this!
