Bonus to Tools (modifying proficiency)

[clavin123]

Sorry if I missed this in another thread, though I searched.

Is there a way to add a bonus to a tool with which a character is proficient?

The only things I seem able to add to a tool are proficiency or double proficiency (aka expertise).

What if I wanted to create a character who had a +2 bonus (on top of proficiency) when playing the Flute? Any way to get the bonus listed with the tool to be Proficiency +2?

(I am reasonably comfortable with the editor, but can't seem to find a field, like exists as the bonus for each skill, to which I can simply incrementally add +2. Am I missing it?)

Thanks.
