// COPIES ALL MEMBERS OF A LIST TO ANOTHER LIST
// --------------------------------------------
// 1. Navigate from https://bsky.app/ to the list you want to copy TO and copy its url
// (e.g. https://bsky.app/profile/bossett.social/lists/3k22v6pbfk32t)
// 2. Change the value of DESTINATION_LIST to your value from 1.
// 3. Navigate from https://bsky.app/ to the list you want to copy FROM
// 4. Open the developer tools, and copy/paste this into the console tab & ENTER
// It may take a little while to run - the page will reload when finished
