How to get candles covered by 'area' object or selected by right-button of mouse?Thank you!

Hi Guys, First, thank you for your very good platform for charting and trading. S# almost fits everything i want for an open trading platform. It is amazing!!!

I am developing a pattern editor and recognizer based on S#.
So candle operation like 'selecting candle series as a pattern' is essential function.
I looked around and found nothing to implement this.

Anyone help?
Thanks.
