Price by view

Hello

I've seen this question several times over the past few years but no real answer.

I sell custom t-shirts.

Price shown is for one side. I would like if the customer wants to customize the other side an additional cost is applied.

I tried by adding on the second view a price on each element (for example 2€) with a maximum price on the view (2€).

The problem is that the price is displayed on each item and as soon as an item is added the price is still displayed. The customer might think he has to pay for each additional item.

I would like the price to show when unlocking the view. Is it possible ? Thanks
