Search for customizing in other customizing

We need to eliminate material groups (MM) in our environment. In order to check where is used the material group ZEB110000 in ABAP programs, we used the standard transaction EWK1.

Now, we need to search for usage of material groups in other customizing in SAP. For example, material group customizing is used as a parameter to customize Characteristic Deviation from COPA (IMG Transaction KEDR)

The where used icon shows more than 400 tables with relationship to material groups, so, there would exist another alternative to do this.

Is there any standard tool to search usage of customizing in other customizing??
