Unfortunately, it isn't possible to create a single hyperlink for the "Equipment" field that automatically brings links to the correct screen depending on the equipment type. The work around for this would be to add multiple hyperlinks to the the field. So for example, on the "Equipment" field, you would add a hyperlink for "Assets", "Positions", and "Systems" or any other equipment screen you would like. This way, when you double click the equipment field, it will give you an option to select the screen you want to go to, and you would select the corresponding screen. Of course, this would require you to know the specific equipment type before hyperlinking.
