SAP and standard email function in Adobe form

In SAP, we're using lifecycle designer 9, We're using standard email function (with a big pushbutton in our form). Ours issues are :

- we're not abble to change dynamically the mail object and body.

- we're not abble to add some secondary receivers in the mail.

Thanks a lot for any solution or idea.

We 've already try with a javascript but it produce a mix objet ...

Best regards,
