Link Task Scheduler "Run now" button/function

Sometimes you want to run a scheduled task in link immediately and outside the planned schedule. As it is now I must change the schedule to ie. 1 minute, wait for it to run, and then change the schedule back. It would be handy with functionality that lets you execute the schedule ad hoc as needed without having to change the schedule back and forth. This could be done with a link or button "run now" or similar.
