I need to set a new layer for a part without actually mirroring it. I have many pin headers already set up on my board and wired up, but I need some of them to face the other way (Set them to bottom layer). This is just an aesthetic feature, but it would be nice to know if I should populate it on top or on the bottom layer. I can't just mirror it, because the pins would be mismatched and would not work.
Is there some way this could be done? Creating a new library part would be a possible solution, but with how many pin headers (and different sizes of them) there are, it would be very time consuming. (But it seems this is the only way so far)
The only thing I want is to print the outline on bottom layer of the silkscreen.
On the attached picture, I need one of them to face the other way, without changing the wiring, if possible.
Edit: I only need the outline of my pin header (what is visible on the silkscreen after manufacturing) to be on the bottom layer. The routing will stay the same.
