Creating new FSx with HDD storagetype in CF

Hello,

We have really been looking forward to the HDD storage-type and now with it being launched we want to try this out and migrate to FSx from our legacy fileshares.

However when reading the CF-documentation here:
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-fsx-filesystem.html

I can see it mentions:

For Windows file systems:
If StorageType=SSD, valid values are 32 GiB - 65,536 GiB (64 TiB).
If StorageType=HDD, valid values are 2000 GiB - 65,536 GiB (64 TiB).

however neither in "AWS::FSx::FileSystem" or in "AWS::FSx::FileSystem WindowsConfiguration" I can find where to specify that parameter to set the FSx resource to the HDD storage-type.

A blocker for us to launch FSx using the HDD-option, would appreciate assistance / how and where to specify storagetype to HDD.
