Cannot select PSCredential UA-variables to use for for PSCredential script parameters

Is your feature request related to a problem? Please describe.
I am not sure whether this is supposed to work and this is a bug, or whether what I want is a feature request. I went with a feature request for now.

We have a lot of scripts (nearly all of them) that take one or more [PSCredential] parameters. E.g.

Param (
    # [ ... truncated ... ]
    [PSCredential]$ADAdmin,
    [PSCredential]$vSphereAdmin,
    [PSCredential]$DatabaseLogin,
    [PSCredential]$ProductXYZAPIKey,
    [PSCredential]$ExchangeAdmin
    # [ ... truncated ... ]
)

and I thought I could declare Secrets (variables) and then select these from a drop-down for all [PSCredential] parameters.
However in UA v.2.1.0 this does not work. I can only select a secret of type PSCredential for the "Run As" field when invoking a script, but that's often useless when multiple credentials are required for a script or when gMSA Accounts are used that can only login on specific servers (and the Universal Automation server is not one of those) or when Credential-variables are passed into remote sessions within the script to solve double-hop authentication issues (e.g. $using:ADAdmin)

Describe the solution you'd like
Being able to select PSCredential secrets via dropdown to fill PSCredential parameters in scripts.

Describe alternatives you've considered
None.

This should work this way. I'll get this resolved in the next build.
