choose which files are in a particular docker volume instead of all

Hi, I've got a quick (hopefully simple) question. I'm using codeserver in docker like mentioned below.
When I add an own volume path like: /home/docker/prometheus/data
it's picking up all the files in it and exposing it to codeserver.
but is it also possible to only picking up the .YAML files for instance?

services:
  codeserver:
    container_name: codeserver
    image: codercom/code-server:latest
    ports:
      - 8090:8080
    volumes:
      - /home/docker/codeserver/data:/home/coder
      - /home/docker/prometheus/data:/home/coder/prometheus
    environment:
      - PASSWORD=xxx
    restart: always

You can mount individual files with Docker (I believe) but I do not think there is a way to mount an entire directory and filter the files. For example:

[code-asher]

    volumes:
      - /home/docker/codeserver/data:/home/coder
      - /home/docker/prometheus/data/file.yaml:/home/coder/prometheus/file.yaml
