purchase from itunes

I have several dozen songs on my "wish list" in the apple store. I cannot find any way to buy them as a group all at once. On a previous purchase of many songs, I clicked on the price of each individual song, one at a time, to buy them. This worked but is very tedious and I expect will ridiculously show up as dozens of separate purchases on my payment method. Can someone advise of a better way? Thanks
