Answer: Formula in B1:G1: (See picture below)

=IF(COLUMN()-1<=SUM(IF(LEFT(A1, FIND("-", A1)-1)=LEFT(List, FIND("-", List)-1), 1, 0))-1, INDEX(List, SMALL(IF((LEFT(A1, FIND("-", A1)-1)=LEFT(List, FIND("-", List)-1))*(A1<>List), ROW(List), ""), COLUMN()-1)), "") + Ctrl+ Shift + Enter. Copied down to A13:G13.
