Handling the default precision on numeric attributes from CAD

Hoping someone might have already solved this one and be willing to share their approach. By default any floating point number passed to an EPMDocument from a CAD file has the precision set to the max (14 I think), which means the value has to show using scientific notation, which is not easy to read. There is a configuration option to ignore precision, but then you lose all precision on all attribute values on all objects, which does not meet our requirements. Ideally I would like to control the display of those particular attributes to limit the number of significant figures, which is going to take some level of customisation. Perhaps modifying the data processor to change rendering for a configured list of attributes, or catching the store of the attribute value and reducing the precision.

Has anyone tackled this issue, able to share any details or lessons learned?
