Multidomain SSL Certificates

Context

As I relaunch my website and blog, I want to make it secure. But I host two different domains on this same site (with a host-based redirect), so I wanted to make sure I could secure both of them. My host’s support team told me I would need to use their “Certificate Signing Request” (CSR) to install an SSL cert but this requires a single common name for the domain name. My question was – how do I generate a CSR for multiple domains?
