Making future events in rss-feed public, just at the event-start-date???

Hallo,

i want to know if it′s possible to set a time in the plugin “events-manager” when future events are showing in the rss feed?

When I post all events at the start of a year every event is immediately showing in the rss feed, but the rss subscriber should only heard about that event at a few days before.
But when a user visit the homepage it should also be possible that he can see all events in the calender or rather in the events-list.

I know this is very challenging problem :-), but maybe there is anyone with an idea.

Thx
