I would say that advertising this pin correctly to the driver is the first step. Trying to make the auto-parser treat this pin better would be a second step, separate from this patch. Making a new model (if that is what you call a "preset") would work as well, and might be easier for this particular case, while improving the auto-parser would be better in the long run.
