"Liveupdate" in NX Journal

Hello,

i'm working at a journal which creates a hugh number of colored points on the workpart. The problem is, that the function "Workpart.Points.CreatePoint" and "NXOpen.Features.PointFeatureBuilder" take most of the time and therefore the journal is slow.
I think one reason is that NX does an update every time a point is created.
So my question is: Is there a way to create points without "updating" NX, and do the update at the end of the journal for all points together?
I hope the journal becomes faster this way...

Thanks.

Johannes
