IAP.GetProductsBySKU does not work for bundle SKUS

Currently IAP.GetProductsBySKU( << list of SKU strings >> )  will not retrieve product information for the SKU used for a Bundle, only for add-ons or subscriptions.  It would be extremely helpful if it worked for Bundles, so we could display the FormattedPrice in our in-app store.  IAP.LaunchCheckoutFlow( < sku >)  works fine for bundles (as well as subscriptions & add-ons), so I wish they would be included in the GetProductsBySKU return data.
