Could you not use the -extfile parameter to the
"openssl x509 -req"
command?  In other words:

$ openssl x509 -req -in <...>.pem -extfile foo.cfg
-extensions v3 ...

and in foo.cfg

[ v3 ]
subjectKeyIdentifier   = hash
basicConstraints       = CA:false
subjectAltName         = DNS:foo.example.com,
URI:sip:foo.com

This works for me, of course, at least for the limited use
that
I put openssl x509 command to.  I cannot speak for the CAs
that
do this for a living on how they put SANs in the CSR they
get.
