Is it possible to have more than one sorts in single IDT query and selecting the sorting variable from dashboard selection?

Hi gurus:

Is it possible to have more than one sorts in single IDT query and selecting the sorting variable from dashboard selection as I want to reduce the load and performance issues that is why I want multiple variables sorting in single query and selecting the sort variable from dashboard selection. Similarly is it possible to have assending and decending sort on same variable and selecting it from dashboard menu?

Need your precious inputs on this.

Thanks:
