Merge a filter

When merging a filter:

1. Hold down the CTRL button on your keyboard, and at the same time click on the filters you want to merge. 
2. The text box on the right, labelled Filter Value will show the last value you selected by default. 
3. This can be typed over to rename the group of merged filters. Note: Select all values before editing the name in the text box, as selecting another value after a new name has been entered will cause the text box to revert to the newly selected value. 
4. Select Merge Value to finalise the merge. Note: The new name cannot be changed once Merge Value has been confirmed. 
5. Do not select Save. Saving now will create a new duplicate value with the name in the box.
