Landed cost of purchase with charge, more than 2 decimal places

Hi All,

When we receive certain items, we put a label on them

I am trying to add to the landed cost of an item, the cost of that label.

we purchase the label in bulk, and the calculated cost per unit is 0,075432, which I want to apply one to each unit received.

However, if I set an Automatic Charge to add the charge per quantity, I can only specify cost as 0.07.

Is there a way to define charges with more decimal points? maybe a different approach to impact landed cost with the cost of labels (and other consumables)?
