In the charactermancer level up for prepared spell casters, players can intuitively choose which spells to prepare from their complete list of class spells, organized by level with inline descriptions. This is much easier than searching through the compendium, even when using filters. It is also much more performance friendly to add only the spells which are prepared than to add all known spells and tick the prepared checkbox next to the ones prepared, especially since adding all known spells doesn't work well when using the charactermancer to level up. Please simply make the spell selection feature of the charactermancer available directly, outside of leveling up.
