I use interactive routing with Altium to route components using Ctrl+W. This normally works well, but I have some castellated holes that are not in the schematic (I created them in the PCB file directly). They are set to the nets they are intended to, but I cannot interactively route to them. The tracks won't lock to the castellated pads:
I have to do it the other way around, from them to the other components like so:
This is a concern because it starts the tracks from the center of the pad, where as I could lock them from their lower edge if I could connect with the interactive routing as seen in first image.
Is there a setting somewhere that could let me connect to pads like these that are not in the schematics?
