I am trying to input in a libreoffice calc file only Mondays and Wednesdays for the next 5 months, but I dont wanna do it typing the dates one by one. So..I thought I would type 4 dates like this:

```
17. Mar. 2014 Monday
19. Mar. 2014 Wednesday
24. Mar. 2014 Monday
26. Mar. 2014 Wednesday
```

Then I thought highlighting these dates and dragging them would give me all the Mondays and Wednesdays up to the a point where I drag it....but this is what I get:

```
17. Mar. 2014 Monday
19. Mar. 2014 Wednesday
24. Mar. 2014 Monday
26. Mar. 2014 Wednesday
18. Mar. 2014 Thursday
20. Mar. 2014 Friday
25. Mar. 2014 Saturday
27. Mar. 2014 Sunday
```

Is there a way for me to put only Mondays and Wednesdays in a fairly simple way instead of typing them one by one?
