Mongoose Reporting Form in CSI

Hello everyone,

I'm trying to make a report form to be size 2x4 and another report size 4x6 when print. However, I couldn't seem to find the property of the form or flex to do this. I tried to adjust the size property but that didn't help. Please let me know if there's an easier way for this. In SSRS there's a page setup where you can do this. I'm new to this reporting form and not sure where.

 

Thank you all for your help.
