Delivery date

[Holohugo]

Hello

We like to have a field, in which we can set exact amount of days for the product availability. We making product to order by hand, so it takes exact amouth of days for certain type of product.

We cant use delivery date field as it is, but we like to modify it, to be able set number of days in which product will be available. Is there any solution for something like that? For now, we are displaying custom text, but we need to send number of days to some XML feeds.

Thanks for any help
