I understand that is I click
" Allowed Products Post - (users can post their own products to this category) "
my merchants (not all customers) can add their products.
 
Can I set the system to specify which categories each individual merchant can add?
 
For example, I may have two merchants with similar products - I would not want to allow both to edit products in the same category as this would allow them to change each others' details!!
 
This any any tips on using the merchant module would be appreciated.

Actually we haven't got a functionality that would allow to sort which merchant can post to which category. But if you send us a support ticket on this, we could think of a customization work.
