Make item prices include the extra cost and not show it only at checkout

Hi sir,

I repeated the topic title of an earlier topic 11 months ago if you don’t mind.
In our country, legislation since 01-2018 forces us to show an item price including all costs whether they are tax or fees. By this law, the customer is protected against hidden costs which they would see when the item must be payed.
I noticed in your reply to that topic that it may be a future addition to your plugin.
Can you please inform me if this feature is already there?

Thanks.
