Grid Lines in Audio Editor. Some q:s..

Hi, I have some questions regarding Grid Lines in the Audio editor.

So, in VariAudio I can only see Grid Lines on the beats. How do I change this to something else, like 16:th´s or whatever?

In Audio Warp I get grid lines on straight 16:th notes. How do I change this if im working with something unrelated to that, like 8th triplet for example?

Can one sync the Arrangement grid resolution to the Audio editors´grid resolution?

A little bit perplexed, I´m sure it´s pilot error to not find ways to alter the grid resolution.

Help greatly appreciated.

Thanks a lot
