How to hide Standard Collection fields?

Hello Experts,

I have a requirement where in, I should be able to hide columns in Savings Metrics Collection, which is under Savings tab of MA.

The Class Reference for this particular collection is 1002.

We have tried to hide them via Page Customization, but no luck.

Can someone put some light on this.

Any help would be appreciated.

Thanks & Regards,

Vignesh
