Rotate Text in a Cell (Numbers) redux

I have a table where the labels are long but the data is short just a digit or 2 so the table can be more compact.

eg.

| Importance | relevance | stage | completion | quantity | rating |

| 1 | 5 | 9 | 4.9 | 10 | .01 |

| 5 | 3 | 9 | 7.4 | 22 | .45 |

| 7 | 8 | 1 | 3.5 | 45 | .33 |

I want to rotate the text in a header row 90° to make the columns more compact so the table can be smaller.

It could be just the same columns with the text inside them slanted.

     |    |    |    |      |     |     |
     |____|____|____|______|_____|_____|     
     |  1 |  5 |  9 |  4.9 | 10  | .01 |
     |  5 |  3 |  9 |  7.4 | 22  | .45 |
     |  7 |  8 |  1 |  3.5 | 45  | .33 |

Or for extra points allow free rotations of the header row to get slanted cells in header rows

I found this post from 2021 that acknowleges that Numbers can't do this (unlike Excel).

Rotate Text in a Cell (Numbers) - Apple Community

However, the user Yellowbox replied and suggested some clever workarounds using text boxes that are rotatable or cell backgrounds that are images of the text aligned vertically instead of horizontally.

Has anything changed since then to Numbers?

How would someone make this as a feature request?
