Sounds like this could work, then:

    ((parent-is "a") parent-bol 2)
    ((parent-is "b") grand-parent 2)

If "a" might also reside not at indentation (with some tokens before 
it), you'll need to decide which indentation to have for that case. 
Maybe the above will be fine, or maybe you could use the 
'standalone-parent' anchor instead.

See treesit-simple-indent-presets for the full list of predefined ones. 
And if none fit exactly, you can define a custom function with the same 
signature (or several) which can do more advanced calculations, 
lookarounds, etc.
