Hi rxemarketing,
We are discussing options along these lines but nothing has been settled just yet.
In the short term, did you know that when viewing the list of events (within the admin environment) you can use options within the Screen Options pull down to change the number of events that are listed on a single page?
By increasing this, you could potentially also make use of the bulk select checkbox to shorten the length of time it takes to select all the events that need to be deleted, particularly if you make use of the filter tool to control the date range of listed events.
Would that work in the interim?
