Additional modifiers for attributes and skills?

[ektoplazm]

Currently there is no way to modify a character by "external force" i.e. by adding homebrew items, traumatic injuries and personal quirks of different characters.

Would it be feasible to add a "modifier" input for all the skills and attributes, maybe somehting similar to the wealth custom modifier? It would have a description and thus there is no need to cover the infinite range of new items/changes to character attributes which can arise during sessions.
