Different watchlists and/or industries have different criterias that are needed. When printing you should be able to save more than one custom layout - would need a save button and a name per layout.

This would also be helpful when wanting to print to a csv file to export to excel, etc - rather than the current print to CSV when right clicking on the viewer - which can not nodify the columns to be printed - thus a custom layout that go to ways - to print or CSV.
