show the value when the spike and the dataset line crosses in the X axis

Sorry, couldn't describe it better in the title, if someone could suggest an edit I'd appreciate.

My point is, when you have multiple datasets and you hover a line, a popup appears in the Y axis of every other line when it crosses the spike line. I'd like to use a feature where it can be shown the popups with the value of both X and Y axis. I'm attaching an image to help to explain my problem:

You see that I hovered the blue line and it showed the popups with the value of the red and cyan lines that met the Y axis, I want to show that same popup in the spot that I have drawn the green arrow indicating the value of the dataset when the line of the dataset and the line of the spike crosses in both axis...

Does anyone know a feature that can do that? Is that feasible? I couldn't find anything about that in the documentation of the spikes.

Thank you very much, great tool you guys developed here!
