Not through the part properties as one normally would unfortunately. Hopefully that will be fixed with the upcoming release. There was a workaround using a separate BOM (I think) but I can't quite remember how that works. If I recall correctly DavidJ may be the one to ask.
Thanks! Using a BOM is the best solution this far, not optimal maybe, but it seems there's no better alternative. Hope they fix it in the upcoming release.
Thanks again bigseb!
Peace
