I cant seem to find clarity on this specific scenario - the best I have found is under the FIFO information but not clear....

Currently have inventory loaded of medical wristbands eg: 10 bands @ R50 ea 

New stock arrived and I want to load additional 10 bands but these were at a R60 cost each

If I use the edit function on the Products and Services Inventory list it only gives me the option to adjust the original starting value.  

Is there another function to load new stock at a different cost?  Thanks
