You can make a collection that has all of your music mods in it and if the collection is publicly visible then it should show up on the workshop page for every individual item. Something like "This item is in a collection by the author" or something, and then it automatically places a link to the collection.

No sorry. I want the modularity of how it's currently set up.

If I need to push out an update in the future to one of these then it would mean that I'd need to merge it all over and put out two updates instead of only one which is a hassle I don't really want to work with, it also makes the asset and txt files something I'd need to actually dig around in to find whatever relevant stuff I'm fixing. Sounds odd but this setup is more comfortable for me and I don't really want the hassle of managing a merged mod in addition.

Hey champ, can you make a mod that contains all of your trailer music mods in one? Thanks!
