I have received another customer complains regarding this RFE.

[RFE] Allow selection of credential on the workflow level.
https://github.com/ansible/awx/issues/7859

Here is the customer's feedback:

I find this extremely disappointing as we would be required to build thousands of templates to cover this extremely poor design decision.
Not an enterprise solution at all in my opinion.

I agree with their opinion though, our product doesn't have methods to specify the credentials dynamically even if we use the secret management system (like AAPRFE-193 that I reported).

At this moment I proposed the temporary solution in order to set the credential dynamically, disassociating and associating the credential on the WFJT node via this API (POST /api/v2/workflow_job_template_nodes/NNN/credentials/).

> Currently we have to manually edit the workflow and set the inventory and credentials on each job if we have to change the inventory or credential.
