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!

The issue names no source file, test, or implementation entry point. Begin with the existing spike documentation and the attached example; define how the popup should report both X and Y values at the cross-axis intersection, then verify the behavior across multiple datasets.
