Use variables that point to a connection's credentials

[petervl]

In a connection I would like to be able to point to the credentials with variables.

We have a credentials folder (synced flat hierarchy) that contains credentials with the name of the server. Those credentials contain the username and password for that server.
I would like to use the credentials from \%servername%.

Is this implemented or still a feature request?
I have a similar request to be able to use variables like %domain% %servername% and %username%
