Disable Synchronization Of All Products Of A Manufacturer From Prestashop To Ebay

[libreriasemola]

Hallo

 

I need to synchronize some of the products of my Prestashop with Ebay.

 

I tried latest official ebay module 1.12 but I cannot see how to avoid all products of a chosen manufacture to be exported.

 

Any suggestion?

 

I know I could change categories of my shop so that some of them can be wholly exported, and some not, but this is not my best option.

 

thanks in advance
