Hello everyone!
I'm preparing a long article and I'm using a multilevel list. By adding captions to pictures I want to have caption like this:

[no. of section].[no. of picture in this section]

e.g:
Section 3.1
[picture]
Pic.3.1.1

The problem is, I want to have different caption for every level of list e.g:

Section 3.1
[picture1]
Pic. 3.1.1

[picture2]
Pic.3.1.2

Section 3.1.1
[picture3]
Pic.3.1.1.1

by adding this last one two earlier automatically change to this third type (one level in caption is added)

Thanks for help,
Paweł
