Create Zone from selection.

Hi everybody.

I want to create a wavetable zone out of small part of the sample should I use external wave editor to cut the sample?

I drop a sample into Halion then select a part of it in the Sample editor, right click → Create Zone from selection, Halion creates new Sample zone out of that small part, I select it in the Program list, go to Zone and change Zone type to Wavetable, Halion creates Wavetable zone out of the whole original sample. So I don’t get the idea.

Thanks.
