Add Directory Double Click

I would like to use a double click to add the contents of a directory to Mp3tag.
Right now I have to single click the directory then click on the OK button.
I've looked high and low for a way to do this, but can't find anything.
It would certainly save a ton of time (and clicks) if I could double click the directory.
Anybody got a way to do this?
Thanks in advance.

I don't know - this is a standard Windows dialogue to select folders... perhaps that dialogue does not allow a double-click in the sense of "select that dialogue" as the double-click is already used to toggle the expansion and hiding of the folder tree nodes.
