REST API: Add operation for updating tasks

Would it be possible to add an operation for updating task settings? We are particularly interested in updating the following properties: "Worksets", "Priority" & "Only on change" (for timed tasks).

Use case:
For the properties mentioned above we have defined default values per task type and want to push these to all tasks at regular intervals as kind of an "autocorrect" functionality. I am aware that we could achieve this via SQL queries as well but would prefer to use the REST API in case table names etc. change in the future.
