checkout progress and breadcrumb

Hi,

I would like to know if it is possible (or at least if you plan to do it) to actualize breadcrumb bar during checkout process ?
i mean if user reviews his cart, why breadcrumb should display: eshop > business cards or anything else, instead of Checkout > Login ?

as you can see in my screenshot, in my case i would be glad to show in breadcrumb what the checkout progress bar shows also...if not, in this case, how can i do to hide breadcrumb when user is in checkout process ?

Because AFAIK i didn't find anything like a different page or item id on which i could hide this breadcrumb on checkout process.

thx
