Why is it not possible to sync the offset of the waveform~ object when changing it from the ruler with the mouse?

It seems strange, have i missed anything? It would be useful, no?

So I have found a solution for those who have the same problem. Use totally transparent dummy waveform and set it to 'loop' mode.

Take the 'selection start' and 'selection out' points to find the average value or middle point then use this value to set the offset of the ruler.

It would still be nice to be able to output it from the waveform~ object. :)
