I am typesetting a letter using Wolfgang's letter module. I have a requirement that is not satisfied by any of the existing styles, namely that the to-address, i.e. the address, and the from-address, i.e., the header, need to start at the same height and be positioned next to one another. I am using the modified style and am trying to adjust the layout via he \setupletterstyle command without success. 

I have look at the sources and have seen how the elements of the various styles are stacked.  All styles use the default style, which defines lefthead and righthead elements, but only the din styles and those styles derived from them seem to use these elements. 

Is there any way to acheive the required side-by-side layout short of cobbling together my own style? Any helpful advice would be greatly appreciated.
