Hi
Thanks for contacting us. So here are the answers please check below:
1: No, sorry, there is no default option to do that. But I will add it to our feature request list so that our DEV team can take care of it.
2: Could you please explain it a bit more? I am not very clear about it. Is it possible to give me a demo of this feature?
3: No sorry, when a product is out of stock, it's impossible to order. See the screenshot below:
