Better Custom Music Discs with Behavior Packs (Bedrock Edition)

Hello, I am not very experienced when it comes to coding so excuse my horrible way of explaining coding language. recently by observing them I have learned a enough about .json files in behavior packs to successfully create decent custom items and blocks in my personal bedrock server. Looking up components and what they do is actually extremely intuitive, and I've been able to recreate similar items like swords and foods as well as making custom recipes and redefining the background music files. I've always wanted to add custom music discs for friends on my server, but there has always been roadblocks (either replacing the sound files cuts off the custom music and removes the original minecraft discs, or that it's impossible to use custom sound events on a custom item with the "minecraft:record" component). I request that the "sound_event" part of the "minecraft:record" component is not limited to only vanilla sound events. This is an issue for at least one other similar component ive seen, and it is really frustrating. Again, I am in no way experienced with this, and maybe there isn't a solution to this problem, and maybe it would just cause more problems to solve by opening it up to custom sound events. Either way, I hope someone sees this because I have really enjoyed slowly figuring out how to make custom items and whatnot, and every time its super discouraging to see certain things locked up like this!!
