Map - Promoting Shapes Made in Microstation - Problem with Arcs and Grouped Holes

Is there a means to eliminate arcs and grouped holes from shapes created in Microstation when they are promoted to features in Map?

Here is the whole process we use, so maybe we can find the best means to alter this process:

We create shapes in Microstation using the Create Region command.  Because we cannot control the source of the original data, the resulting shapes include arcs and grouped holes. 

These microstation elements are referenced into a Map Model and Promoted into map features.  When these features are then used in various overlay processes, the arcs and grouped holes cause errors in the data.

What is the most efficient means to convert the arc edges of the shapes into faceted lines, and to split the shapes at any internal shapes so they are not grouped holes?
