Campaign Monitor Subscription field (checkbox)

Hello,

I saw a topic about Mailchimp Subscription field (checkbox).
My question is similar but with Campaign Monitor integration.

In a certain form with fields (name, email, etc.) if the user choose a “newsletter subscrition” field (checkbox), then it’s name, email, any chosen field is sent to the proper list in Campaign Monitor, if he does not check the box nothing is send to Campaign Monitor.

Is it possible ? now ? How ?
or maybe later as it was suggested in Mailchimp Subscription field (checkbox) topic ?

Thanks.
