Add modifier key to sometimes override Middle-click to close a program on the taskbar

EDIT: Never mind, I found that there Advanced options and I was able to do it there.

Please delete this idea! :-)
==============================

Hi there.

I use the setting to allow middle-click to close a window 99% of the time, for example, I have 6 Windows Exporer windows open, and I want to close a few of them, so middle-click on the ones I don't want - life saver!

But ocassionally I want to open one or two more, so need to right-click on one of them and select Windows Explorer. What I would like to do is be able to select a modifier key (Shift, Ctrl, Alt, Win) that temporarily disables middle-click to close, and instead reverts it to its default function of middle-click to spawn a new program instance.

Can you please add this!
