Revenue Cloud - Quote Line editor - Add products

Hi everyone! 

I was wondering if there is a simple way to add products by searching in the list of all products in the revenue cloud quote line item editor? 

I can add them from browse catalogue or the search whenever the product exists in a catalogue.  

But I want to be able to search all products with the revenue cloud quote line editor without necessarily having them be added to a catalogue.  

Is this possible? 

Thank you!
