Credential Linking

Currently I need to create several credentials that have different usernames or domains but use the same password. It would be very helpful to create a credential with just the password and then link that credential to the other credentials in the password field, this way I only need to change the password credential one time and not in every credential that uses the same password.

Credentials Examples - these all three share the same password but are used for different purposes

Example 1:
Username = My Username
Domain = My Domain
Password = My Password

Example 2:
Username = My Domain\My Username
Domain = ( Domain needs to be in the username instead )
Password = My Password

Example 3:
Username = My Username2
Domain = My Domain
Password = My Password


Proposal:
Credential: PasswordCredential
Username = <Leave Blank>
Domain = <Leave Blank>
Password = My Password

Example 1:
Username = My Username
Domain = My Domain
Password = Links to Credential Named "PasswordCredential"

Example 2:
Username = My Domain\My Username
Domain = ( Domain needs to be in the username instead )
Password = Links to Credential Named "PasswordCredential"

Example 3:
Username = My Username2
Domain = My Domain
Password = Links to Credential Named "PasswordCredential"

This concept would be helpful for username and domain as well where i created a username credential only and that is linked, same for Domain.

Also, when I create the credential that is username\domain, it would helpful to enter username\linked domain

Thx.
