Exporting data from PCMCS with DM how do I round the output values to 2 decimal places

Summary

round exported values from PCMCS to export file

There does not appear to be a way to export values from PCMCS with DM, so that the values are rounded to 2 decimal places.

The documentation refers to the Data Precision and Data number of Decimal.  We set both of these to 2 and still values come out with 12 decimal places.  I believe for ASO cubes these are invalid according to the note in the documentation.  

"These settings works only in BSO cubes; they do not work in ASO cubes."

There is another reference to using SQL Mapping in data load maps code but it's only for ARCS.
