Automatically with - no, I don't think so. Automatically with a script - 
yes.

You should change
<dia:object type="Standard - Polygon"
to
<dia:object type="Standard - Box"

Then instead of
<dia:attribute name="poly_points">
        ...
</dia:attribute>

You would need to add:
<dia:attribute name="elem_corner">
<dia:point val="..."/>
</dia:attribute>
<dia:attribute name="elem_width">
<dia:real val="..."/>
</dia:attribute>
<dia:attribute name="elem_height">
<dia:real val="..."/>
</dia:attribute>

But you would need to calculate those values. "elem_corner" would 
probably be the easiest as this should be the same as "obj_pos". Height 
would be max(Y)-min(Y) and width would be max(X)-min(X). By X and Y I 
mean sets of x and y coordinates of "poly_points".
