I have hundreds of programmes in a dropdown list, but quite often users need to exclude/include certain programmes. These are not predefined, so I cannot hard code/use 'select exclude' using a button. Is there a way users can add these specific programmes to a 'excluded list' instead of selecting all programmes except one or two?
The users can select the one or two programmes that they want to exclude. Then they can right-click on the list and choose "Select Excluded". This will select the majority of the list that they want, excluding the two that they originally had selected.
