Expression to chage credential dinamicly for IA

The idea is:

It would be great if it were possible to use expressions in the credential to dynamically change the credential when using a single workflow with multiple users.

My use case:

the workflow can change any credential if the workflow have mult users like saas project using single workflow

I think it would be beneficial to add this because:

we don need create several workflow with n8n when we are working wih some project with mulple users thaat only use the app front-end, we can save resources

Any resources to support this?

Are you willing to work on this?
