this is actually why dendron's note reference syntax is rather verbose:

yml
(( 
    ref:[[name]]#anchor1:#anchor2
))

i want it to support more exotic references and operators moving forward

yml
(( 
    ref:[[foo.csv]],
    startLine: 2,
    endLine: 5
))

some other operators:

yml
startRegex: /^foo/  # use for anything
startKey: fooKey # use for yaml and frontmatter
startHTMLId: ... # use for <span> tags inside markdown to reference arbitrary sentences
