Ability for Super Admin to Impersonate Super Admin

I am posting this request on behalf of our customer Ideagen.

Ideagen would like the ability for their super admins to impersonate other super admins. 

“The use case is that not within Gainsight we have different Admin responsibilities which we are segregating by Permission Bundles. Some Admins are going only to create email templates, survey, success plans, etc. and some will be distributing them via JO programme. For me to see whether I assigned their permissions correctly and didn't give too much navigation, it would be very helpful to be able to impersonate Admins too.”
