I don't know about Kickad, but in Eagle you can do it in two ways; or by selecting the JUMPER item from the library and selecting the appropriate length element in it. Another option is to go to the other side of the path (elements) - it is good to determine the size of the via and its diameter right away.
And how to make a jumper in kicad? because I read here on the forum and also on another that it is impossible to make a jumper in this program.
KiCad's symbol libraries contain several jumpers. On the other hand, you select the footprint from the "Wire_connections_bridges" library and adjust the dimensions of the pads to your needs (the footprint length does not change).
KiCad is so convenient that after selecting the so-called In the footprint, you can also edit the shape and size of the pads (and, if necessary, the size of the hole). This is what I like about this program.
I put a version of the board with two indicator drivers on one PCB, maybe someone will need it ... One connection should be made underneath with a cable (marked in red in the second picture). There are also incorrect "-" and "+" markings next to the bridge, initially the PCB was to be powered from symmetrical DC voltage, I added the bridge then and I forgot to remove the markings. The thermal transfer file is now valid.
