Supporting same day delivery with carrier service min & max delivery dates

Hi there,

we currently built an app leveraging the carrier service. https://shopify.dev/api/admin-rest/2021-10/resources/carrierservice#top

We provide a same day delivery service - we actually deliver products in 3 hours or less.

When we populate min_delivery_date and max_delivery_date for the same day, we realize that Shopify does not show any additional text in the shipping method description in the shop checkout. It seems Shopify only takes these fields into account when the date in 2 days in the future.

Do you have any information if Shopify will support the display of same day delivery in the checkout through these fields?

Thanks for all your help!

Best
Philip
