Display Stock on Hand Balance on Item Button

I love the 86 list function... but the system should also allow the display of SOH balance on the item button if its not displaying the 86 list value

Ideally it should be an option to display SOH Balance on the item button if the item is not on the 86 list

we use the 86 list for items we make (often different quantities each day).. we need SOH balance to display for retail items that we buy in and are stored.
