Changing slides without changing another cue

I have just been using worship extreme for a short while. Each week I create a new cue list by copying last week's cue list. Then I change the slides in the opening psalm and sermon scripture (I do this manually because Worship extreme doesn't have the versions we use in our church.) I just realized that this changes that slide in the previous cues as well. Is there any way to manually change the slides for THIS week without it changing previous cue lists as well?

You would need to create a copy of the slides presentation first. From the "Slides" menu at the top, find the presentation, right click and choose "Duplicate". Then choose the new duplicated presentation as the slides foreground for the cue.

Thank you! I thought I had tried that, but I guess not. I did what you suggested and it seemed to work this time.
