Boot sysnand from fusee-primary - SX core chip

Hey all - recently set up my patched Erista Switch with Spacecraft-NX firmware on the SX Core chip to load Hekate and chainload either fusee-primary or sysMMC from there.

With it's current setup, the Switch needs a payload injected otherwise it can't boot anything - so I wondered if there was a way to set up fusee-primary to boot stock from sysMMC, with a hotkey or something, rather than having to chainload through Hekate in order to be able to boot both?

 

Thanks no worries - I've already got Hekate set up fine chainloading fusee-primary as well as stock sysMMC but was just curious to see if there was a way to skip an unnecessary step in the boot process. Not a fan of the "AIO" packages as I'd much rather take the time to set it up myself.
