ArivBy Estimated Delivery Date

I searched for a long time for an app where I can set different delivery dates for different variants of the same product. The app works great and is very easy to use.

However, I am still missing an option to set the restock date. The product is manufactured in another country, and our warehouse is restocked once a month. It would be great to add this specific date, similar to how it works on Amazon.

This way, customers can purchase the product knowing in advance that it will arrive at our warehouse in, for example, two weeks, and this time automatically decreases each day.
