Subscription Offers for new users ?

Hi,

We are currently using the auto-renew subscription in our app. I would like to implement subscriptions offers for my auto-renew subscriptions, with promotional code for new customers.

Unfortunately these offers are only available for lapsed subscribers or retaining current subscribers. But for my marketing needs, I would like these offers to be available to new users.
Is it possible ? How ? Google play provide this feature for new customers.

I also looked at the introductory offers, the problem with this one is that there is no way to lock introductory price only for a some specific users. If so, how could we target some specific users based on specific criteria.

How can we make a discounted subscriptions only for some specific users ?

Regards,
