Make Scribble on iPadOS takes input per character like in watchOS

Is there's a way to make Scribble on iPadOS to work like in watchOS where it takes input per character, not per-certain-pause-period?

I'm making a crossword App for iPad, and it gonna be really cool if the user can just write each character inside each box in a very rapid way just like we did on a real physical crossword puzzle.
There is a solution to this, that I have noticed in another crossword app (made by the Swedish broadcasting company, actually).
  1. When you click a box, the app will highlight the horizonal row of boxes.

  2. If you click the same box again, the app will hightlight the vertical row of boxes. (And if you click it again, it will start over from step 1.)

  3. When you start writing, it will enter letters from the box you clicked and further on to the right/bottom.
