Mix n matching Marketplace behavior packs

I want the ability to put multiple marketplace behavior packs from different worlds into one world or realm. Like if you wanted to make a epic realm for your friends take the behavior packs from marketplace packs that add, one that adds new mobs, one that adds new TNT, and that adds lucky blocks for instance. This could be implemented by insuring that the packs are owned and you have to be signed into your Microsoft account to use them if they are packs included with realms plus. This needs to come to bedrock edition because you can kinda already do this on pc by messing with the game files but us console players can't do it so pls add this Mojang!
