That is correct. I am not aware of a possibility to get the data and the 
signature from GnuPG. But that doesn't mean it's not possible. AFAIK 
there is no difference in the signature in both cases. So it should be 
easy to patch GnuPG in order to get this data (if there isn't another 
OpenPGP implementation which offers this action).

Use both ways (one step, two steps) to sign and encrypt a file and have 
a look at the result with gpg --list-packets.
