How to line up duplicated values on same row?

for example,

2018        totalsale    2019        totalsale
brand a     2,000        brand b     10,000
brand b     3,000        brand d     5,000
brand c     4,000        brand a     2,500
brand e     3,000        brand f     3,000

desired result

2018        totalsale    2019        totalsale
brand a     2,000        brand a     2,500
brand b     3,000        brand b     10,000
brand c     4,000        
                         brand d     5,000
brand e     3,000
                         brand f     3,000

I tried to use append and merge in power query like this video suggests https://www.youtube.com/watch?v=v2OaYuxlm54, but the totalsale didn't follow.

Are there simpler ways to achieve this goal like excel formula and something else? Thank you for all answers.
