Possible to launch rapidminer on OSX w/ R extension without manual command line?

I am using OSX with rapidminer and the R Extension.

I have R_HOME and JAVA_HOME both set, launching via "java -jar <path to rapidminer>/lib/rapidminer.jar" works fine.  But if I double click rapidminer's jar it does not come up with the R extension.  Is there a way to make it so I can use the R extension and not have to manually launch rapidminer via the CLI?

Also, I have both R and R64 installed, how can I tell which version is integrated with rapidminer?  I have a feeling its using the 32-bit version but I want to use the 64-bit, here is the output from rapidminer's R perspective:
