Draw Traces: pandapower.plotting.plotly.create_line_trace, legend question

[portal-cat]

When I use create_line_trace to create lines, many lines will be displayed in the legend of the final drawing (after draw_traces). Can we hide the lines in legend? (such as "showlegend=False" similar to the plotly) Or use "legendgroup" to show only one line in legend?

And also for the create_bus_trace, can we hide some buses in legend? Thank you!

This should be solved by PR #1511
However, create_bus_trace was not modified. Could you please specify the desired behaviour? We also welcome pull requests if you can propose an implementation
