Update: the extlist plugin does have a way to set list block class (eg.
~~ol:hierarchical~~), but doesn’t mention alpha or roman numeral lists on the wiki page.
However, in the plugin’s css files, i found a class named alphabet, but the code
~~ol:alphabet~~ does nothing. If i had a working computer, i would inspect and modify the css, but i am using an old iPad, and not really sure how to do this here.
If anyone has a tip on how to make it work, i’ll be grateful. 😅
For now i have simply updated my document like this:
* (a) Sub A
* (b) Sub B
Which works somewhat. I also made a new issue on the plugin page, hoping the developer will be able to fix it.
