Certificate request should use the original values, not the CA ones

[scop]

I generated a key pair, generate the certificate request and got the CA reply (COMODO).
After i imported the CA reply, the certificate fields changes to "CN=(certficate name) OU=GGSSL Domain SSL, OU=Domain Control Validated" because the CA enforce this info.

Now, i want to renew the certificate, reusing the same key, but i can not, because the Generate certificate request uses those fields instead of the original. When i try to submit the CRS, the site complains that several fields are "wrong", forcing me to always recreate a keypair.

So please allow one to choose what certificate fields to use, the original ones or the CA enforced ones.
