It would be very useful to have a "Poll Now" feature that causes the script trigger to begin polling.
As it is now, you must either wait or manually configure the project's schedule to be sooner (and then change it back after testing).

The "Poll Now" feature is currently available for SCM triggers, and it should work identically to that functionality.
The "Poll Now" option would go right above the "ScriptTrigger Log" option with the same icon except with a little green play triangle (at least if the goal is to match the SCM trigger mechanism identically).

Thanks!
