Scaleing a microstation cell


I am current using the latest microstation v8i select version and having a problem with scaling a dgn drawing.

I currently have a cell that I have which is 1100’ x 1700’ with a scale of 1:1. What I would like is to have this cell changed to a 24”x36” and insert this into a dwg with 1”=50’

How would I do this?
