issue with finder's tabs

[filmar23]

My request is (I hope so) very simple: I WANT that every time I open a new folder it will automatically merge with the others finder's windows that are already opened. Basically one folder with n tabs.
I already use the command Finder> Window > Merge All Windows but I wish it was automatic .
Thanks to those who want to help me.

EDIT: maybe a listener that every tot seconds merge the windows?

Instead of opening a new window (cmd-N), just open a new tab (cmd-T). It's easy.

if I have a finder window open in background the new window will not merge. This is the point.
