Custom SCM, Multiple Desired Values

Hi all - I am working on creating custom SCM content. Using the Custom SCM wizard, I am able to create fixlets/analysis with a single desired value. However, I cannot figure out how to include multiple relevance statements, and multiple desired values (for example, to check two registry keys which both need to be set for a single compliance check). Can this be done through the wizard? Or is there a way to edit the fixlet/analysis to use multiple desired values? There is non-custom SCM content which can accomplish this, I am just not sure how to replicate this myself.
