Feature request - Internal task or subtask approval feature

If you could include an approval/sign functionality to validate tasks or to read notice tasks, this would be great.

For instance: in Wordflows steps could be approved by another teammate/supervisor and would be registered such as, other use for instance employees that have to evaluation resumes or internal educational task duties. So with this Approval/signature option we could give internal validations and force that certain tasks or jobs has to be approved, learned, read etc.

If this could be included in a report even better. So the project or company or HR supervisor could see if all members has read, confirmed, approved certain tasks.

These tasks should of be blocked to changes in cases of requests of confirming just Read or Approval in case of employee reports, validations etc.

Maybe Select Custom Field may be a perfect fit here
