Dynamic Scoreboard Comparisons in Target Selectors

The Suggestion: Currently, target selectors for scores are "static," meaning we have to manually input a specific number (like scores={score=5}). I am proposing the ability for a selector to dynamically compare a score on a target entity to a score on the player or executor running the command. Example Syntax: @e[type=armor_stand, scores={id=@s}] (This would select only the armor stand whose "id" score matches the executor's "id" score.) Why this is needed: 1. Multiplayer Scalability: Currently, creating systems that link a player to a specific "data entity" (like a pet, an NPC, or a personal HUD display) requires massive, laggy command chains to check every possible ID combination. 2. Dynamic UI/Titleraw: It would allow a single titleraw/tellraw command to pull information (like custom rank names) from a specific entity tied to that player, instead of needing 50+ command blocks for every possible rank/color.
