Instead of using your entire Measurement Chart for ERB and e-commerce - you might want to have some Measurement tags you can use on your Measurement Chart.

In Admin-Sizes you can set up your Tags - just click on "Add measurement Tag"

This will create a new row in your list of Tags.

Give your Tag an ID - if needed and a unique name.

Save your Tag and you are good to go.

Read here how to use these tags on your Measurement chart.
