Filing a flightplan via SITA

[OPS_1]

Hello!

Here is my question. Is it possible when filing a flightplan via SITA to add AFTN adresses outside of the IFPZ which will receive a copy of the transmitted flightplan message? Does there exist a special SITA message format?
I don't have my own AFTN connection. Just SITA.
