That's how it is done in debian packages. The full text of each license is only mentioned once and given an identifier which is then used to link the license to the relevant copyright statements. For example: https://salsa.debian.org/debian/highlight/-/blob/94ee655915518d22669ad8341b212b0653c3b563/debian/copyright https://salsa.debian.org/debian/highlight/-/blob/94ee6559155...
