Printing over 800" document

I have a Epson SC-T3475 24" x 200’ roll paper. I am trying to print one single sheet of my document. I can not get past the preset document size. It allows me to set the 24" Vertical Only allows me to go to 236.22″. I need to be able to go way pass that at least 708.66" or even more.

Despite Please increase or delete page size limit in Draw - #2 by mikekaganski is about Draw, the limit is defined by the same settings available in Expert Configuration.

Note that it’s called Expert Configuration for a good reason.

Ok, this is way above my knowledge base.
