I would like to request a "Re-select all" capability in anything selection related.
In the selection tool, if selections are already made, the "Select possible" option is deactivated, even though the actual "possible" values are fewer than the currently selected due to selections in other fields. I see no reason for this deactivation. The user should be able to reselect possible. Maybe make it a seperate option.
A strong pro argument is that the functionality already exists with calculated dimensions. Suppose I have a calculated dimension named "Segment" based on the field [Customer Code]. If I make a selection on "Segment", some [Customer Code]s are selected. If I do other stuff (without removing the original [Customer Code] selection), and I again select a value from "Segment" (which has now changed due to its dynamic nature), the Customer Code selection gets updated with the new possible values but having also considered the previous selection - so a "Reselect all" has been made.
This functionality will be very useful in multi-step calculations.
