[FeatureRequest]: Dual Z Endstop missing

[nolsnols]

Is your feature request related to a problem? Please describe.

I have independant dual Z and dual Y drives with endstops.
The Endstop tab is showing only X,Y,Z and if one of the Z endstop is triggered it is not clear, which endstop is triggered.

Describe the solution you propose.

It would be great if de Z2 and Y2 endstops will show in the plugin.

Describe alternatives you've considered

Ex. A workaround exists but it is tedius, for example...

Provide any additional context or information.

Ex. Photos, mockups, etc.
