setSortImgState can only set one column's sort img.

Hi.
I want sort by two or more column, the first column sort asc, the second colun sort desc…
And i sort in the server. So i want use use setSortImgState to change these columns’s image.
But i found only the last setSortImgState will have effect. dhtmlxGrid only can show one sort arrow.
So, better let dhtmlxGrid can show more than one sort arrow in the header.
Thanks.

dhtmlxGrid only can show one sort arrow.
Unfortunately this is the designed behavior and we’re not planning to change it in the near future.
But your request is registered and will be discussed.
Thank you.
