Count number placements among actions leading to fast finish mode

[spanezz]

In this example situation¹ it's clear that the game is basically solved: placing a 2 and a 1 on the top right and then resolving the single pencil mark squares would in turn remove other pencil marks leading all the way to completion of the puzzle.

Once fast finish mode activates, it's kind of fun to tap on all the squares, but activating it here requires 5 long presses: two to fill the 2% cage, and 3 for fast finish mode to trigger. That makes the game a big unpleasant, as I find long presses somewhat stressful on my finger joints.

The new "Check nishio" feature wouldn't trigger here, as there are various squares with multiple pencil marks. In theory the game engine could see that if all single-pencil-mark cells got filled the game would cascade to completion, but for now I would propose a simpler way to reduce long presses:

Could the act of placing a number via a long press count towards triggering fast finish mode?
