I did watch the video, and maybe this is useful in some cases, but I do not see how this plugin helps in this particular case. Especially the manual renaming of the vias makes it cumbersome.
Try this.
Move mouse cursor on one track end, press x to start a track.
Press v to start placing a via.
Press f to finish the track.
Another way is to first spread the tracks apart a bit, and then simply place via’s on top of the tracks. Then they will be automatically be part of the same net.
But more importantly. it is often bad practice to place vias too close together. If you have a GND plane around the via’s, then you should place the via’s far enough apart from each other so the GND can connect in between the via’s. Interruptions in the GND plane should always be kept to a minimum.
