Microsoft Points & Pre-Orders

Hi all,

I'm assuming the answer to this is no, but I wondered if you could help anyway.

I have some Microsoft Points I can convert to a voucher, but wondered if I would be able to use said voucher on a pre order?

Essentially, I'm looking to save the points to cash in for a voucher to get a discount on GTA 6 next year. I know it's only valid for 90 following redemption so I won't be doing it yet as it will expire well before the games release, but I'm HOPING I can do this leading up to the game being out.

Anyways, thoughts please people?
