Ascending dates in column

[SuperBrain]

How do I add dates with ascending month values to a column. I can add dates with ascending day values by adding a date at the top and clicking the small black button at the bottom right of the box and dragging it down to how-ever many cells I want. I cant figure out how to get it to change the month value instead of the day value.

When you put two dates with ascending month in the first two cells, e.g. "01.01.2021" in A1 and "01.02.2021" in A2, then select both cells and drag the black button down, you get what you want.
