create user.micro merge to each colorscheme without create them under user colorscheme folder

I have implement org highlight with syntax/org.yaml

filetype: org

detect:
    filename: "\\.org$"

rules:
      # headlines
    - headline:  "^\\*+ .*"
    - priority:  "^\\*+ (\\[.+\\] |[A-Z]+ )+"

      # comment
    - comment: "# .*"

      # tables
    - table: "[[:space:]]*\\|.+\\|"

      # bold italic delete underline mono
    - emphasize: "\\*[^ *][^*]*[^ *]\\*"
    - italic: "/[^ ].*[^ ]/"
    - delete: "\\+[^ ].*[^ ]\\+"
    - underline: "_[^ ].*[^ ]_"
    - mono: "[=~][^ =~].*[^ =~][^=~]"

      # lists
    - list: "^([[:space:]]*[+-] |^[[:space:]]*[0-9a-zA-Z]+[).] )(\\[.\\] )?"

      # links
    - link: "\\[(\\[[^]]+\\]){1,2}\\]"

      # urls
    - url: "https?://[^ )>]+"

      # block
    - block:
        start: "^#\\+begin_.*"
        end: "^#\\+end_[^ ]*"
        rules: []
    - block: "^#\\+.*"

and create colorscheme/user.micro

color-link headline "bold #282828,#E6DB74"
color-link priority "#CB4B16,#282828"
color-link table "#66D9EF,#282828"
color-link emphasize "bold #AE81FF,#282828"
color-link italic "#E6DB74,#282828"
color-link mono "#ABE674,#282828"
color-link delete "#505050,#282828"
color-link underline "#BDE6AD,#282828"
color-link list "#F92672,#282828"
color-link link "#CB4B16,#282828"
color-link url "bold #CB4B16,#282828"
color-link block "#C6EF74,#282828"

and copy every buildin colorscheme file to micro user colorscheme folder, then append 'include "user"' to every .micro file. is there a way to avoid create so much duplicated files and merge user.micro to any colorscheme selected, maybe an option?

Start by examining colorscheme/user.micro, the built-in colorscheme files, and how their include directives are handled. Determine where selected colorschemes are loaded, then define the smallest change that applies user colors without duplicating every .micro file; done means the user rules appear with any selected built-in colorscheme.
