Second display on DFR0676

Hello,  

I would like to attach a second ePaper display to the DFR0676, for a picture viewer.  I plan to use a Spectra 6 display from WaveShare or GooDisplay. The reasoning is that the DFR0676 already has a SD card slot, so my picture viewer can be fed both from the interwebs and from the SD card.  Additional advantages are that the DFR0676 has a On/Off switch and buttons that can be put out to the front of the case.  In fact, I plan to use the DFR0676 as the base of my case, and will only display diagnostics information on it. 

The Spectra 6 display comes with 8 connectors, Vcc, Gnd,  and six pins for the SPI interface.

The DFR0676 display uses the primary (HW?) SPI and the SD card uses the secondary (SW?) SPI.  I would like to use the display and the SD card independently, so I would prefer to attach my second display to the primary SPI  (with separate CS),  or to another separate software SPI.  It looks like the primary SPI pins that drive the 2.13 display are not brought out to the PCB.  

Looking for recommendations on how to connect, which pins on the DFR0676 could be used, and maybe for some software example that declare a new software SPI.

Thank you!
