How to 2 arches 50 pixels each one port

[Randy Martin]

Setting up my prop in PE S4.  How do I set up Prop in the Preview with 2 arches with 50 pixels each daisy chained together and then connected to 0ne port (E1.31).

I can set it up as 2 separate 50 pixel arches on 2 different ports but want to only use one port.

Easy to do in pixel editor.   First arch.   Universe number  1  ( whatever you choose).   Start channel 1 . End channel 150.   Second arch.  Universe number 1. (Same as first arch. ).      Start channel.   151.  End channel 300
