Multiple Geometries to a Series

Hi Everyone,

Would anyone know how I can apply two or more different geometries to a grid series so they appear instead of just one appearing in the output.

To clarify, on the GH file attached I've applied two different skewed boxes onto a series, however, only one output shows up at a time. I was hoping to use the random input to allow both to appear on the series of boxes in a randomised order, but when changing the seed number it only cycles back and forth between the geometries.

Does anyone have any advice or know how to fix this?

Thanks in advance.

Chris
