Item status 'No Sales' / filtering which items can be added to Quote/Sales Order

We manufacture electronic products that we also sell to customers.

We have set up various item classes for the components (electronics, mechanical etc.) and have created a separate item class for the finished items.

We don’t want to the sales team to accidently add a subassembly or component to a quote/sales order - to minimise errors. The finished items item class is essentially for all of the items on our price list.

It was an idea to set everything in the ‘finished items’ item class to Active, and to set all of the items in the various other item classes to No Sales.

But it doesn’t seem to be possible to define the default Item Status in the Item Class settings?

Whenever a new stock item is added, regardless of the item class, the default status is Active and it would need to be changed to No Sales each time?
