Can you copy the settings from my former feed manager?

You can configure Sellermania, like your former feed manager. 
To set up the same parameters, you need to list the specifics that you provided to your previous feed manager. (e.g. price rule, categorisation rule, exclusion rule, specific comment per marketplace).

This will be used for the configuration in Smart Map, which consists of writing the matching rules between your product flow and the data expected by the marketplaces.
