When assiging commands to a device, it would by very nice to multiselect the property values. I came accross this while working around the %d% limitation of not being able to 0 pad it.
My hardware interface defines three commands for volume: Volume, Volume0 and Volume00. 0-9 get assigned to Volume00, 10-99 to Volume0, etc. I have to individually select each value from 10 to 99 and assign the Volume0 command to it. To make things worse, the list box scrolls back to the first value after I assign the command!
