Open Studio Radiance Measure Capability and Limitation

Hello, I am new to learn Open Studio and EnergyPlus.

Recently, I want to have a daylight autonomy distribution result from my building model simulation.

I use open studio and energy plus to develop my building model, would it be possible for me to get the Daylight Autonomy Distribution from the radiance measure result?

As I know from the experience using the Radiance measure, I only could get the accumulated spatial daylight autonomy for area in my illuminance map.

I also read several question in UnmetHours like this, but I still don't understand the limitation and capabilities of radiance measure provided in Open Studio.

Does the radiance measure allow the user to change the daylight parameter calculation inside it such as changing the occupied hour and illuminance limit for the daylight autonomy distribution or is it limited to the IESNA standard (300 lux, 08.00 - 17.00) ?

If my model has a non-rectangular shape, can I obtain the accurate sDA calculation in open studio considering the limitation of rectangular illuminance map in the software?

Thank you for your consideration to answer my question.
