Is it possible to see when the workflow task is going to be retried next time?

Say we have a Workflow Task failing due to improper code, and it continues to fail again and again.
For example, it’s 15th attempt already. Is it possible to know when this is going to execute the next retry? Also, it would be a good thing if it were possible to manually trigger workflow task (for example, once we’ve fixed the code and want this fix to take place)?

Thanks for the request, good idea.
