The Source box now offers a drop down which contains the same options as the Source box on the Profile tab, if the caption matches the caption on the Profile tab. If the caption of the Source field on the Position tab differs from the caption of the Source field on the Profile tab, you may set up a different list of options. Please contact a BlackDog support representative for assistance.
The drop down is optional. To toggle it on/off, press the F11 key on your keyboard when in Add, Change or Find mode.
See the screen shots of the Position tab and Profile tab for the location of the Source field.
