Grouping of combo boxes for tax and tracking codes

When offering more than one item in a Sales Quote or Invoice then you have an option to select a tax class for each item. A default value can be set in settings that applies to all items but that does not cover my topic.
I would like to see an option to link all the combo boxes together so when you change one then you change all of them.
This would apply to Tax class, tracking codes etc.
A simple check-box on top of each column would select linking and when one combo box is changed after ticking that combo box then all of them get the same value.
