Allow event start date range configuration within promotions

For end of year, we had a campaign running where customers who bought an event in a specific month/location could get 1 ticket for free. Currently, we had to select all the events for that month/location 1 by 1. Very time consuming and error sensitive.

Allow that event range (from/till start date) can be configured in ‘Applies To’ section when setting up a promo campaign.
