Multiple timeslots in quick mode for class based calendar

Is it possible to have a quick mode for multiple selection of timeslots? Here is the situation:
90mins per class; 2 classes a day (morning and evening)
Mon, Wed, Fri morning for class A, evening for class B;
Tue, Thu morning for class B, evening for class A;
recurring by week, (or month as an option)
(Schedule is set by "service specific work hours")

Right now, the customers need to select "Service" -> (skipped staff selection) -> "Date" -> "Timeslot", and "Add Service", and again and again..."Service" -> "Date" -> "Timeslot" -> "Add Service"... "Service" -> "Date" -> "Timeslot" -> "Add Service"...

Proposal 1 (Date and Service):
"Date" -> "Timeslot 1", "Timeslot 2" -> Next -> "Add Service", and so on (as screenshot, HTML edited)

Proposal 2 (List mode by service per month):
"Service" -> (List Mode) "Timeslot 1" (1st Monday), "Timeslot 2" (2nd Monday), "Timeslot 3" (3rd Monday), "Timeslot 4" (4th Monday) -> "Next" -> "Add Service" -> "Service" -> "Timeslot 1" (1st Friday), "Timeslot 2" (2nd Friday), "Timeslot 3" (3rd Friday), "Timeslot 4" (4th Friday)

I understand the plugin doesnt really generate the timeslots, but list the timeslots and only occupie the timeslot when booked. This is the difference with the class based booking.
On the other hand, classes generation usually end every month, and may change every month. Mon, Wed, Fri morning for class A may change to Tue, Thu morning. Some doesnt have the classes for next month until the middle/ end of the month. Therefore, "Period available for booking in advance" may not be applied for classes.

Thank you very much in advanced!
