How do I link two petitions?

[Chris Michael]

Hi All,

I need my petition to send to 52 recipients. Change has a 40-recipient maximum. I contacted their support. Change says that I can "link" two petitions so that the signatures in one petition flow into a second petition. So I can put 40 recipients in the main publicized petition, and I can put 11 recipients in the secondary unpublicized petition.

Unfortunately, Change has not explained how to do this. Can anyone help? Is there existing documentation on this?

Thank you so much in advance.

Sincerely,

Chris
