Particularly useful when you are wanting a product to show up when more than one value is picked in the filters, currently the Specifications table will show every value, separated by a comma, which can make things look messy when there are a lot of values to a feature.
If we had an additional tick box, like the "display on search" (which means the feature is used as a filter currently), but saying "display in specifications", then you could turn them off.
In the example attached, the product shows up if you filter for Black or Grey "Colour Group" but the actual colour (Finish) is Gunmetal, which you would still display in the specifications box, just omitting the table Row "Colour Group" completely from the specifications table.
Lots of applications to the logic I believe, for example
If you were selling a USB Flash Drive, you could filter for USB Flash Drive, Memory Stick, Thumb Drive, Removable Storage (so regardless of what the customer knew it as, they would find it), without having the row in specifications with it all in.
