All queries and distributions work as filters. This means that the sets of bugs they contain may change depending on which element the filter is applied to.
Deskzilla allows to move and copy queries in the navigation area under different elements filtering bugs contained in those elements.
To move a query or a distribution under a different element, select it in the navigation area by clicking on it and then drag it to the required location. As the element is dragged over the navigation area the possible new locations are highlighted with red. Once the required location is highlighted drop the element.
To copy a query or a distribution, right-click on it and select Copy. Then right-click the element, that should be the "parent" of your query copy and select Paste.
