[Feature Request] Obsidian Spell Sheet Custom Spell School

By default the 5e spell schools (divination, abjuration, necromancy etc) are all well and good but do not fit into every game. Especially when it comes to homebrew settings.

The spell item template sheet makes one of these 5e schools a mandatory choice.

It would be nice to have a "custom" option for spell school to input schools, so that we can add things like Psionics or other custom schools.
