Hello,
I think I might be able to help you out here... How exactly you implement this depends on what type of services you have. I'm at an ELCA church and we're fairly liturgical, meaning our order of service has a fair amount of elements. If you use a more contemporary format, this might actually be even easier.
Basically, I have scenes setup for each part in the order of service, for example my scene list would start with scenes for Prelude, Gathering Hymn, Greeting, Confession, Kyrie, Canticle of Praise, First Reading, etc. Notice that my scenes are generic items, not the names of the actual items, for examples the my scene is named "Gathering Hymn" not the name of the actual hymn, and the first reading is "First Reading" not the Bible reference.
To go along with these items, I have a folder structure setup for the current week that contains a folder for each of these items, again generically named.
For each of the scenes, I setup the camera and sound settings, then an image slide show, also generically named (so the slides for the Gathering Song are named Gathering Song Slides, First Reading Slides, etc.) then I point the slide show to the directory of the same name in the current week folder. THEN I setup the hot keys.
For each week, I put the slides in their appropriate folders, then I'm ready to go. For scenes that just need a title slide, I keep all of those in one folder. Something I learned is that you will want to have OBS closed when you are updating the slides, if you don't they won't go in the right order.
We have communion every other week, so I have a Scene Collection setup for the two different service formats.
This takes a little bit of work to get initially setup, but it makes the weekly work so much easier.
If you use a more contemporary format and have multiple songs back to back, just put them all in one scene and slide show. You don't really gain anything by keeping them separate, UNELSS you want different settings.
If you want to see how this turns out, look up St John's Evangelical Lutheran Church in Madrid, Iowa on Facebook. Every so often I miss switching out a slide or the wrong one gets assigned, but I can't really do anything about it during the service since I'm also the organist, so someone else actually runs the live stream.
With all of that said, I would still welcome a feature that would default the hot keys for all slide shows as well. I would also prefer that slide shows were set to manual by default. I can't imagine that most people want their slides to be automatic, but I suppose it's possible!
