I downloaded a single and now I want to buy an album with that song. Is there a way to get rid of the single so I can have all of the songs under one album?

I recently downloaded a single and now I want to buy an album that includes that song. Is there a way to get rid of the single so I can have all of the songs under one album? It will not give me the song as a duplicate if I download it right now.

I just want to get rid of the old song since it was a single and get the whole album. Basically just deeting the song from my purchases (figuratively speaking). Like I never owned it.

(OR) Is there a way to turn off complete my album?
