Reusing Groups

Will it be possible at some point in the future to re-use a group of slides?

Here's our situation:

For three out of four Sundays, we use basically the same liturgy. On the third Sunday of each month, we use a different liturgy. For the three Sundays that have the same liturgy, I copy the presentation and make the minor tweaks that are needed (hymns, texts, and announcements). For the one time per month that we use the different liturgy, I copy the previous month's presentation and do the same thing. Where it gets tedious is with the announcements. As the weeks progress, there are only a few announcement changes, so it isn't a big thing. Over the course of a month though, most of the previous month's announcements no longer apply and I'm redoing most of the work I've done over the past three weeks over again to insert the updated announcements. If I could just re-use the Announcement Grouping that I've created in a previous week's presentation, it would speed things up greatly.

Another use would be when we insert liturgical elements like Healing rites or Affirmation of Baptism rites which we use regularly and contain multiple service elements. Being able to insert the grouping from a previous presentation would speed up the presentation preparation on those weeks.
