Forma Multi Column view - anyone know how to modify it?

Hello, I really like reading two columns in landscape mode on the Forma, but while I can do that during the day, the maximum font size is too small for me to read at night. It seems that the Forma automatically defaults to a single column at the font selection of 8th from the smallest. Does anyone know how to modify this?

I'm curious if there is an edit to Adobe's Reader software that could be made, or if there is an edit one could make to individual epubs. Is there something in the style sheets that controls how this displays?

I imagine I could install KSM and KOReader and perhaps get this functionality, but I'm hesitant to do so because I am NOT a coder and I don't want to risk bricking a device that doesn't have a removable SD card...

I should make it clear, this only works with side-loaded epubs - kepubs always display as a single column.

If anyone has any insight, I'd be most appreciative!

Thanks,
