Reuse actors in ray.wait

For the following code snippet.

while not_ready:
    print("Not ready")
    ready, not_ready = ray.wait(not_ready, num_returns=1)
    print(ray.get(ready))

After doing ray.get(), if the ready actors are idle can we add it to not_ready list with some data to process . In order to utilize the actors fully . Can it be done ? Is it a good practice.
