There's a trick, you cannot. Turns out you have two compendiums, aigis compendium and the one you carried over from the original game. You switch between them in the velvet room, you can only purchase from the one that's from og. Heartless removes the switcher, and you have just aigis compendium, it's prefilled up to 25 lvl, though. I ended up starting the game on hard, searching difficulty, lvl, and money addresses. Then I raised lvl to 99 and money to 9,999,999 gradually bought out and registered the entire compendium, reverted lvl to 25 and money to 3000, then set difficulty to heartless. The downside is the compendium gets a lot cheaper, and you open all aigis teurgies from the beginning of the game.
For me on a microsoft store version of the game values for difficulty were (easy 17578, normal 33962, hard 66730, heartless 132266). It's easy to find once you know them, you just need to change difficulty a few times. Had to fight a bit to raise a lvl once and find the address as well.
