Hi @TheFrenchWitch ,
Thank you for reaching out to the Community.
While I can completely understand the impact of this not being available natively, the Shopify App Store would be the best course of action here. I’d recommend checking out the app called 'Connected Inventory’, as it may work for your business needs. I will however, be sure to pass this feedback along to our Developers. We’re always looking for ways to improve the platform and appreciate these suggestions.
Please let me know if you have any other questions!
