Custom license update automation

From time to time my custom license gets some updates, for example this time to include terms about using the work in NFT’s and crypto art. This was the second time this year I had to go through 75 model pages, manually paste in new text and save the page (time consuming).

Would it be possible to have some “separate” custom license upload container (that could hold multiple license types) and have some option to point to them from a list? So basically upload ones, select ones, update ones?
