Selector combinator: increase/decrease quality

[Metaflame]

TL;DR

New Selector combinator mode to increase or decrease quality

What?

A new quality change mode ("Modify quality"?), which would step up or step down quality for every signal individually. Increasing Legendary or decreasing Normal would remove the signal.

Why?

Currently, increasing or decreasing quality takes multiple selector and other combinators. Since selector combinators already support transferring quality and filtering by quality, being able to increase/decrease quality would be great. One use case is finding existing matching items of a lower quality, for example to recycle and re-craft for a chance at a better product.
