Is it possible to Restrict certain Customers created within Sage 300 with specific group code from getting inserted or synced to CRM?

SOLVED

Hello,

Is there any method/setting, that can ‘Restrict’ certain Customers (with specific Group code) that are created within Sage 300 from getting into CRM as company record? 

I know that if we tick the  suspend A/R integration to CRM checkbox from E/W setup, the company record is not created in CRM. But that will not add ANY company. 

How to avoid Customers with a certain group code to get inserted in Sage CRM ??

Is that possible?

Please advise.

Thanks
