How to put down a group of dates in a table?

Question

Spreadsheets

The essence of the problem: when stretching a group with a date, the dates are not put down as needed, but simply copied.

You need to stretch "group_1" with one date so that other groups have the next date.

It should be like this:
- Group_1
1.1.22
1.1.22
- Group_2
2.1.22
2.1.22

It turns out like this:
- Group_1
1.1.22
1.1.22
- Group_2
1.1.22
1.1.22
