Is your feature request related to a problem? Please describe.

Yes. Sometimes I have many custom certificates that I use in NPM, and when they are expired, it's hard to find which host is using the certificate or if there is any host at all is using any certificate

Describe the solution you'd like

It would be great to show a count of how many hosts using each certificate

Describe alternatives you've considered

N/A, I have to manually find out from the hosts which certificate being used
