API / Webhook for Carousel Message Template

This Carousel Message Template was released around 4-5 months ago, but I still can't use this feature effectively due to the absence of an API or webhook. Every time I send this template, I have to upload all 10 images manually, which is time-consuming, especially for just one or two recipients. I even tried setting it up as a chatbot template message, but it didn't work due to the 24-hour restriction.

Please consider providing an API or webhook to simplify the setup and help us utilize this feature effectively.

Thank you
