Same SSL Certificate on two HTTPS bindings of the same domain?

Hey IIS gurus,

Does anyone know if it's possible to put the same SSL certificate on two https bindings with the same domain name?

We currently have an SSL certificate on https://domainA.com:444

I found a manual work around to make IIS give me another https binding with the same domain which isn't possible with the GUI via CMD to give me https://domainA.com on port 80.

Now domainA on port 80 has a self signed certificate from IIS. DomainA on port 444 has a real certificate from our CA.

Is it possible to make the port 80 domainA have the same SSL cert as the port 444 one?

If I try to give it the real cert in IIS it says it's going to remove it from the other HTTPS binding of 444.
