Paypal - Increase expiration date of subscription

[SuNcO]

We are using Paypal Express Checkout buttons to create subscriptions.. all fine, we use IPT and PDT (even Sync Api)

Now, we want to reward users that fills surveys and other stuff

Is there a way to increase the expiration date or next billing date ?

Can't find something on the docs or googling

I think the only way to shift the next billing date is to suspend the subscription.

For e.g. you could suspend a subscription till one day after the next billing date to skip one billing cycle.

Could somebody confirm if thats the way to go here?
