Unused REFCLK and GXB Pins

The Cyclone IV GX Schematic Review Worksheet says to tie all unused REFCLKn pins to GND through a 10K resistor, and the unused REFCLKp pins to GND through a 10K resistor. The same goes for unused GX...

I don't have a lot a space on my board and I am wondering if I can use only 2 x 10k resistors.

I would like to use use 1 resistor per bank (QL0, QL1) to connect all unused GXB_RXn, GXB_RXp together?

Is it possible ? Or each signal type needs it own resistor ?
