I'm not sure I understand this notion of an "anchored" interval. However, we can specify how an interval is anchored WRT the time specified by postposing a PU after the ZEhA, thus: ze'apu a medium interval, extending before the referenced point ze'aca a medium interval, centered on the referenced point ze'aba a medium interval, extending after the referenced point Does this do what you want?
