Sticky lines could show up for large data definition as well

Hello,

Currently, as it seems, for Python code, sticky lines shows up for classes and function names.

Sometimes I need to edit very large data structures (nested dicts/lists). Would it be possible to add sticky lines to them as well? I imagine it would make it easier to navigate such a data structure (seeing, like breadcrumbs, where I am in a nested dict, for example).

Best,
