Cross Plant Config Material Characteristics Value Change

Hi Experts

We are using Cross Plant config Material in Basic Data 2 and MRP3 views. In the configure variant tab, we need to do mass change of characteristics values.

I found CLMM t-code for class characteristics values mass change. But this doesn't allow the above config related characteristics value.

Can anyone help me how I can change the characteristics values inside the Configure variant tab in mass.

Also would like to know which table will have these values. It is not found in AUSP table.
