delay recurring payments and adding existing payments

[Virtus]

2 Questions, figured I would wrap them all into one post.

 

Question 1.) How could I go about delaying a monthly recurring payment for 2 months? That is to say, have it so that it does not charge them a recurring fee for 2 months after payment. It will only have an initial fee charged at time of purchase.

 

Question 2.) We have a large amount of people already subscribed through authorize.net. Is there a way I can add these people to WHMCS one way or another...preferable an automated easy way. I'm php capable so if I have to write my own script I can.

 

Thanks
