To move a sub-item of one station to another station, perform the following.
STEP 1. Open ForeFlight and open the Aircraft W&B profile you want to edit.
STEP 2. Select the LOAD button in the left column on the bottom.
STEP 3. Select EDIT just to the left of the LOAD button.
STEP 4. Find the line item you want to move.
STEP 5. Tap and hold on the three lines to the right of the line item description. A shadow will appear under the line Item meaning it is selected to move.
STEP 6. Swipe your finger to move the line Item to another Station. Drop the Line Item by removing your finger from the screen.
It is helpful to know that when moving a line item from one station to another that the arm used for that line item will be the one associated with the station it is under and not the old station.
Notice the CG shift between the images caused by shifting the weight of the line item to another Station.
