Google Play: if a user already has a subscription, can promo-code applying to delay the next payment date?

Viewed 71

Is there any other way to gift a PRO user with a free subs day? The motivation here: we want to make a "gift for continuous subs" - if a user is a PRO user for 3 months in a row, he receives an extra month for free (or something like that). Now we need to find technical ways to implement it.
