YES THERE IS...you need to add a cc_config.xml file to the Boinc data directory that looks like this:
<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

The file MUST be done in Notepad in Windows, other programs add characters and the file won't work. Second you need to attach a 2nd monitor to the 2nd card on pc startup or make yourself a dummy plug to make it think there is a monitor hooked up to it. You will also probably have to load the AMD software twice, once for each gpu, to make Boinc see both of them. Remember to exit and then restart Boinc after each step as you get it set up.
