multi select event in coupons

I want to allow administrator to select multiple events in coupons tab and want to give discount on the bases of selected events.

please help me.

Hi

At the moment, the extension only allows you to use the coupon for ALL events or only particular event and it is not possible to select multiple event. I will consider adding support for this feature in future release.

I have modified component with multi select events and got the event id on checkout page but it only calculates one event discount.
How to calculate other events discounts and where to modify code in component (which file).
Please suggest
