Signing All Digital Signatures at a time

HI ,

1) My first question is about a requirement in which all the digital signatures in the form should be signed by click of a single button"SignAll".Is this functionality possible in Adobe 11?( am designing the form in Adobe LiveCycle Designer)

2) If i place a digital signature in the form, when the user clicks on the digital signature feilds a window pops-up and he can sign the form there, now i have a question this , can i place a button adjacent to the signature feild which the user can click (intead of the signature feild).and onclick of the button the signature window pops-up(which pops-up for afer the user clicks on signature feild earlier) i.e. the button should do the functionality of the digital signature feild and finally the signature should appear in the signature feild that i have placed in the form .

Thanks,

Bhaskar.
