I want to check and operate invisible edges

If the rendering style is shading or hidden lines, it is not possible to understand hidden edges. For example, in the case of Sketch feature, is there any way to check this? Also, is it possible to input blends, etc. to the hidden edges?

Reproduced Steps:
1. Create a Sketch and extrude it

2. Create a Block feature on top of the extruded feature( with Unite)

When selecting sketch geometries, only the visible sketch lines are highlighted.

“Selection” group – “Highlight Hidden Edges”
Highlight a hidden edges by selecting an edge in the model or a feature in the part navigator.

“Selection” group – “Allow Selection of Hidden Edges”
Hidden edges can be selected while performing various commands (for example, Edge Blend).
