Which kind of resouce should be setted for the working tables, moulds in Factory Flow Simulation?

Hello everyone, In my simulation scenario, there are several working tables which is used to mount or clean the product and a mould which is used to form the product. I have setted their resouce type as User-Defined, but it is impossible to create product zone for the User-Defined Resouce. My question is which type sould be setted for the working tables and moulds in Factory Flow Simulaiton?

With Best Regards
