How to do TMP Monospacing in Unity 6

I had monospacing on some TextMeshPro - Text(UI) components in a Unity project I just updated to Unity 6. The letters were monospaced before, now they are not.

I think this is because before there was a property on the component for monospacing the text, which now I can’t find. (I haven’t gone back to check, but I think it was under text style). It looks like the <mspace=x> tag works, but it would be a lot better in my case if I could set it on the component.
(I’m guessing I’m either just not seeing it, or it got removed)

Thanks.

Would you not pick a monospace font?

I could do that, but there was an option before where it would allow you to monospace any font by adding padding to each glyph so they would be the same width (this still exist, using the mspace tag, but it was more conveinient to have it as an option on the TMP component).
