Yes, there is, actually.
Inside the same directory as the benchmark program you can find all the optimized apps themselves. This is half of what you need already - the other half is inside the "XML" subdirectory.
Best practice: run your cache on BOINC dry (meaning set BOINC to "no new tasks" and let it finish all it has). Then, stop BOINC - if you're running it as a service, you'll need to run "net stop boinc" in a dos box or from start/run, otherwise just closing the BOINC manager should work.
So, when you ran the test, it suggested an app to use. Copy that app to BOINC\projects\setiathome.berkeley.edu, then look inside the XML\ subdir I mentioned above and copy the file with the same name as the app itself (like: SaH_5.15_KWSN_SSE2-PM_Ben-Joe_2.0_B.exe is the app, XML\SaH_5.15_KWSN_SSE2-PM_Ben-Joe_2.0_B.exe.app_info.xml is the corresponding XML file) to BOINC\projects\setiathome.berkeley.edu. After copying this file, the last important step is to rename the .xml from "SaH_5.15_KWSN_SSE2-PM_Ben-Joe_2.0_B.exe.app_info.xml" to just "app_info.xml".
Or - you could just take note of which app it suggested and download that app separately from
here.
Now start BOINC again, and don't forget to allow new tasks.
Happy crunching,
Simon.
