multiple handshake messages in a single TLSPlaintext record

[Yannay Alon-BAY004]

Hi 
 
I want to use openssl to send several handshake messages in a single tls
fragment. (e.g. serverhello + serverkeyexchange + serverhellodone in a
PSK ciphersuite)

In the words of rfc 4346 section 6.2.1: "multiple client messages of the
same ContentType MAY be coalesced into a single TLSPlaintext record,
..."

Does anyone know if this is supported by openssl? fully, partially or
planned to be?

Thanks

Alon
