We often show similar sets of announcements in pre and post-service across multiple services and special events during the week. I'd like to be able to create independent Announcement Sets that can be added as an item to any given presentation. It could perhaps behave as a folder where you could tweak transitions / slides within the announcement set, and those changes would apply anywhere that is using the set (or an independent interface where you update them would be fine as well). We may still have a few one-off slides for any given service that we'd want to add outside of the set, so the transitions should account for all announcement slides in the case of timer-based transitions.
In addition, it would be great if I could set an "expiration date" on a given announcement slide in a set which would result in its auto-removal from the set. This would help ensure any slides representing old events are automatically removed / not shown during presentations. You could optionally just mark them as not shown but keep them included, but I'd be fine with having them removed completely.
