Combine 8 single bin/hex programs into 1 hex/bin file

[NickC]

i dump some algos from my old neunaber slate pedal (no more in production and have no support) which was now giving me problems, now i'd like to combine them in my dual eeprom octagon. Has anyone tried this yet?
The individual programs works on my octagon but I would like to have more available on the same custom eeprom.
