Suggestion - Limit per category products.

Suggestion: if there is a way to set limit per category of uploading products.

For example:

If Home&Garden contains 30 000 products you can choose limit of 10 000 to upload or custom number. So you can count how many products are always be in your shop from chosen category. Newest products are with priority over oldest one.

Also - Not available products should be deleted permanently but they are not. I can see how from 50k products, 15k are unavailable or not in stock.
