I am often making parts that have two planes of symmetry, for example tables, or other furniture. I always find myself making a feature, then having to mirror it across one plane of symmetry, and then go select the original and copied item and mirror them against the second plane of symmetry. I haven't found a way to mirror a feature across two planes of symmetry at once, and I wish I could.

Even better, perhaps, would be if I could make both the front and right plane dynamic mirror planes at the same time (this is when I am sketching in top plane). As far as I can tell, this is not possible. Does anyone have an idea how I can do this, or something simillar?
