Can you use another mechanism rather then attributes?

For instance, we would like to determine this at runtime rather than as an attribute decoration in source code.
- Concurrent vs Nonconcurrent
- Queue Name

We would like to be able to define for a specific job which queue it should run in, whether it is concurrent (in that queue) or can run in parallel and other attributes that we currently have to provide before the job is even compiled.

If this was answered somewhere else, would you point me there please? So far I've not found it if it exists.

TIA
