How to anchor panel between rows?

Hello,
Is there a way to anchor panel (e.g. text panel) between rows?
I’d like to create sections of rows e.g.
CPU STATS
row1
row 2
row 3
TRAFFIC STATS
row 4
row 5
row 6
etc.

The problem is, when I collapse row 3 text pannel with “TRAFFIC STATS” disappears and from now is included in row 3. So it looks like this:
CPU STATS
row 1
row 2
row 3
row 4

Regards,
Mike
