Would it be possible to add a “Select/Deselect All” checkbox to the selection screen in Custom Mode and Advanced Search when defining a measure? To be placed in the area below “Filter”.
That way you could either select all at the beginning, or filter by keywords and select all results that are returned, instead of having to click one by one. This especially applies, because it doesn’t seem that I can use “Shift-Click” to select everything in between two values on this screen.
