quotes module - search product filters and search options

Hi.

Can someone point me to where I change the search criteria and filters in the search products window of quotes.

I set my products and categories and added necessary search criteria within products advanced search… My sales team need to find these products to add to a quote but the standard layout of rows and criteria is pretty poor so makes it unusable.

I cant see anywhere I can amend this. Looked in the quotes module of module builder but cant see anything relevant. Any help please?
