Input scoreboard value for parameter (commands)

Sometimes when doing stuff with commands, I wish I could just input the value from a players scoreboard entry. It would also be useful to store a player value under a scoreboard entry. For instance, if I was trying to create something that could use the /structure command to save a structure with the name of the chunk I'm in (example: "chunk: 3, -7"). This could be solved if we made some modifications to the way scoreboards work. I could possibly use "[score:@s,chunkx]" to pull the value of chunkx for myself. This could look like "/structure save "chunk: [score:@s,chunkx], [score:@s,chunky]" ~-8 0 ~-8 ~7 256 ~7 disk". This is just a basic use for this. If this is possible, it is probably possible to include the same for a generic player value, such as "[value:@s,x]" which would pull the players x position. If this was added I would honestly be so happy, as I have run into many problems where I have to use long, repetitive workarounds that usually work the amount of times I copy-paste the commands.
