Formating text options missing in MS4

Hello. In MS4 I am no longer able to define the style showed in Fig. 1 in my classical guitar scores. To do this, I need: a) the thickness of the border equal 0 (in MS4 it goes only to 0.1), b) the highlight option, in order to define the background color (highlight is gone in MS4), c) the alpha channel in colors (no alpha channel in MS4) and d) the corner radius going to values at last 15 (now it goes until only 5 in MS4). MS3 was more sophisticated regarding formatting (Fig 2) than MS4 (Fig 3). I am trying to mimic the formatting for fingering present in Dorico, where the text interrupts the line, for better reading. I was successful in MS3 (Fig 1). No more in MS4. How can I reproduce the fingering sowed in Fig1 in MS4? Thanks in advance.
