Ramses boundary particles

Hi, As other Ramses user probably know, sometimes particles can end up at the box boundaries, which effectively means they have left the simulation volume. I've noticed however that when reading in a Ramses snapshot, YT tends to keep the particles at the lower end of the boundaries (e.g. x =< 0 in c.u.), but removes all beyond the upper end (e.g. x >= 1. in c.u.). This may significantly bias the centre of mass when calculated using particles. Thus my question is: How do I tell YT to either ignore or include all boundary particles when loading a snapshot? Cheers Thor.
