Can we purchase multiple copies (at one go) of same product id without multiple authentication popups?

Question

We have implemented non-renewing subscriptions in an iOS app. There are different packs with different product Ids. We would like to purchase multiple quantities of the same pack / product id, by leveraging queuing, at one go.

But when we do so the authentication pop-up shows up multiple times.

For example, if we order 3 copies of the pack / product id, then the authentication popup shows up 3 times, even though the order was via a single request submission.

This obviously is very bad user experience.

Is it possible to purchase multiple quantities of the same product id but not get multiple authentication pop-ups?

Please help with this.
