Can you send parameters to the command-line "analyse" function?

I'd like to make further use of dotCover's command line coverage reporting, but to use it in all of our environments I need to have the ability to pass in a parameter, specifically for the Executable parameter.  Is it possible to do this without a static file?

For example, something like:

dotCover analyse -executable x:\tools\nunit-console.exe -arguments MyDll.dll -workingDir c:\ -output output.xml

I suppose the filters would pose a problem here but until there's a custom NAnt tag it would be great to have an interim solution.

Thanks!
