straighten a flat hole after continuous dome feature

I'm trying to get a dome out of a rectangular shape and the only smooth result is achieved using the continuous dome feature. Loft, sweep curve with guide, boundary surface... all of them create a visible fringe (same fringe appear when continuous dome is unchecked)
The problem is that when continous dome is used the hole in the center is no more flat. I would like to straighten the hole to get a flat hole, and I would like to have no fringe.
How can it be done?

Resp. Sir.

Actually, when any radius profile (DOME) cut by Straight line, it generate Curve, even it solid of surface.
I Try to solve your problem in different way also and attach it.

This is the final solution :)
You want a dome, but a dome is an elliptical-shaped generation. You want a flat surface with a rectangle at the top of the dome ... impossible. You have to pass from one form to the other but I am sure of the best solution to get there. You will have a dome at + -90%. See sldprt file and step
