job-exec volumes tied to sql_instance only?

I'd like to create a Job, not a Service, so I used to job-exec submodule. I'd like to mount a bucket into my job, which is not a problem using the console GUI.

But this module only allows SQL instances for volume mounting. Am I missing something?

The v2 module allows for all kinds of volumes, identical to the console GUI, but it's creating only services, not jobs.
