So it looks like this info is being lost somewhere in the conversion pipeline. I don't know if this is due to technical diffilculties or is just that CHM conversion is still maturing, but it looks as though the OP's request may be possible.
Sounds like time for the OP to check the Bug List and file one (attaching the chm file) if there is not one already.
