Is there a way to modify the parameters in the STWBC GUI to get a range closer to 25mm?

[LRolf.0]

I'm looking to use the ISB044V1 to transmit power beyond the recomended 3+5mm. I've tried changing some of the parameters through the GUI provided with the STEVAL-ISB044V1, but I have been unable to get any additional range out of it. Realistically, I am hoping to accomplish close to 25mm of range between the transmit coil, and the receiver coil.
