So If you want to assign a command pick list to only one hotkey use this command. In the parameter tab you can add the individual commands. There you can move the command items up or down to change their order in which they will be displayed on the pick list.

Choose a descriptive word(s) to be displayed in the command pick list.

Click on the checkbox on the left to enable or disable the command. Disabling the command will omit it from the command pick list.
