Is it possible to have different in stock numbers for product for each sales channel?

Is it possible to have different in stock numbers for product for each sales channel by default in shopware?

Are there any such plugins?

Is it possible to do through coding? Any clues?

Hi, 

This function is currently not implemented. 
A plugin for multiple stocks is also not available yet.
You can do this by coding or check if a shopware 5 Plugin is going to be available for shopware 6 soon.
