Is there a way to always show the method signature containing the caret at the top of the editor

In PyCharm, I've noticed that when the caret moves through a large json file, a listing of the containing objects appears at the top of the editor. This would be very useful in CLion if method signatures (while in cpp) and class inheritance lists (while in h) were shown.

I searched through Preferences and Help but couldn't find a way to enable such a feature. Does it exist or can I vote for it?
