Affinity Designer - Correct Vertical Alignment of Captial Text in rectangle

[GreyEyes]

For Affinity Designer:

 

When creating a button for a screen, you add a rectangle and then add a text label, say in capitals, like: CANCEL

 

When you come to centre the text within the rectangle (button) using the vertical alignment tool, it doesn't centre virtually correctly, as it's factoring the font height including below the font baseline, so manual adjustment is required.

If you are not using lowercase lettering and only capitals, then ideally it should centre virtually align based on the actual visible height of font, not the defined font height including below the fonts baseline, especially if you are using capitals and not lowercase lettering like: g, j, p, q & y

How do you end up centering text in a button then? As there is no vertical alignment option it seems rather fiddly. Have you come up with a consistent workflow?
