How to Flip Brush/Group of Brushes in Torque Constructor?

Is there any way to flip a brush or a group of brushes in Torque Constructor? I see translate, rotate, and scale tools, but no flip tool. Does the tool not exist, or am I missing something?

Example:

Scale to -1 on whatever axis you want to mirror.

Example:

Thank you! I had tried doing this earlier, but Constructor crashed, so I thought it didn't support scaling by negative numbers. It turned out that the problem was I used the arrow buttons to decrease the scale from 1 to 0.1 to 0, and Constructor crashes if you try to scale by 0. For any people that run into this problem in the future, type in -1 rather than using the arrow buttons.

Thanks, this will come in really handy! Never thought of scaling by negative numbers
