Can we configure staff and contact password to have both a number and a special character?

Summary

Configure staff and contact password to have minimum of one number and one special character

Content

We have a requirement to configure the passwords for the staff account and contacts to include minimum of one number and one special character.

With the current options we can set the minimum special character, but the minimum number and special character are clubbed together so it will accept either of them. But we need one number and one special character minimum in the password.

Is this possible?
