Favorites List for product selection

I'm a fuel delivery driver using GoCanvas for delivery ticket entry's.  When I make a delivery one of the steps is to select the product ID delivered.  We have a very long list of IDs and while some of the most commonly used IDs (based on the whole company, not individual user) are at the top of the list there are many times I have to use the search to find the right one.  I only deal with a 4 or 5 different IDs daily.  I would like to have a "Favorites list" that I can create and edit from the app as needed.  When the Product ID pick list first shows up it can show my favorites first, then at the bottom have a option to "Show All"
