At one point I sat down and created a Character Journal and a Rollable Table with token images for each of the main summons I'd be using. Then created a drop-down query that ultimately would provide a one-click button to roll the stats or attacks for any of the summons. Combining this, it provides a "Character" with tokens for each monster, stats, and attacks that you can import into games from the Character Vault (Plus subscription required) Tedious as hell to setup, but infinitely useful for a summoning character. Without a Plus subscription (or wanting to go through that setup), your best bet is probably keeping a set of physical Cue-Cards like you would at a physical game. One-side for the monster's stats, the other for its attacks. Create a card for every summon you could see yourself using.
