I can quickly build you an hex for any of the lights that are currently building for rev 721, which are, in alphabetical order:
emisar-2ch
emisar-d4sv2-219
emisar-d4sv2
emisar-d4v2-219
emisar-d4v2
noctigon-dm11-boost
noctigon-kr4-219b
noctigon-kr4-219
noctigon-kr4-2ch
noctigon-kr4
noctigon-kr4-nofet
sofirn-lt1s-pro
sofirn-sc21-pro
wurkkos-fc13
wurkkos-ts10
wurkkos-ts11
wurkkos-ts25
If you want any/all of them, just give me a holler and I will put a ZIP up on my webserver for you to download.
EDIT: decided to go ahead and made a zip file with all these hexes, anyone interested can download it here: https://durval.com/xfer-only/anduril.ALL_HEXES_THAT_BUILD_-_multi-channel_branch_rev_721+8C_quick_aux_switch_20230616.zip
Never tried as I configure my TS10 and FC13 to remove Simple mode and start directly in advanced 
but looking at the code, I can see it’s not enabled under SImple mode, just advanced.
