I think this could quite easily be made into a single DTML method that
can be called on any document. You can pass all parameters to another
Method by passing the namespace variable "_" to it. Perhaps your method
could be something like:

<dtml-call
expr="RESPONSE.setHeader('content-type','application/octet-stream')">
<dtml-call expr="RESPONSE.setHeader('Content-Disposition','Attachment;
Filename=%s.html' % document)">
<dtml-return expr="StepReport(_.None, _)">
