Need help in adding German titles and descriptions

We have our primary store in the UK which is connected to all other European stores. We are trying to updated local german titles and descriptions for our german store. We tried the edit listings option but it wont reflect on the frontend because it is connected to the UK store.

We reached out to customer support and they advised us to delete and relist the products again to update the german titles and description. But what we encountered was when we delete a product from our german store it gets deleted in the UK store as well and when we relist it Amazon gives a new SKU for the product which has caused it not sync with our inventory management platform.

Is there a way to update german update titles and descriptions without it being affected in the UK store?

If deleting and relisting is the only option how can we solve the integration issue?
