nested json array formatting

[MochaSteve256]

I don't know if i'm dumb, but i don't think this is currently possible.
I want the pretty-printing of th e dump() function to accept a parameter that specifies in what nesting level newlines are inserted.
Like, if i do this using dump(4):
{ "blocks": [ [ 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 63, 0, 0, 0 ], [....
...which is quite unreadable. It should be able to only insert newlines when a new "blocks" item is appended rather than whenever an item in an array within the "blocks" array.

Ok, in this view it removes all the newline's. But hopefully you see what i mean
