Suggest add support with multiple sessions setexitonclose

Now SQX only support to Exit At End of Day ,and End of Day Exit Time is only one.
But in some instuments,there may be two or more sessions in one day,for example, 9:00-15:00 and 21:00-23:30  etc,and in every end of these sessions we all need to cover  the open  position.
So,suggest SQX can give some custom options.
Exit At end of sessions1  (switch ), 
End of session1 Exit time(  15:00  )，
Exit At end of sessions2 (switch ), 
End of session2 Exit time(  23:30  )，


The exact number of Sessions Exit time can custom by user.


Thank you.
