I have important questions regarding the plugin

Hello,

I am contacting you because I am a customer of yours, and I am in the process of configuring your plugin on my site.
However, there are some settings that I can’t change, and I would like to know if it’s possible to access this type of configuration on your plugin.

Problem 1:
– We are unable to limit the quantities of products on the stages. Indeed, we want to put a minimum and a maximum quantity on certain products.

Problem 2:
– I want to select several different quantities and products on the same step without the page starting to load when I add a product. How should I do it ?

Problem 3:

I would like to add a different description to each step.

I therefore ask you if it is possible to answer my questions, and provide me with the necessary solutions so that we can finish the plugin configurations.
