Generate-certificate copy all SAN's

Hi, I’m doing the following;

My HAproxy is listening for HTTPS and terminates it;

bind *:443 ssl crt <cert> generate-certifictes ca-sign-file <ca-sign-file>

It copies the Common Name and one Subject Alt Name into the generated certificate. For example, Facebook, it has one SAN with the value

But, when looking into facebook’s original certificate; it has more than one SAN:

Is it possible to copy all the SAN’s into my generated certificate?
