Oh, actually somebody added such functionality to Toolshed:
https://sourceforge.net/p/toolshed/code/ci/default/tree/libdecb/libdecbopen.c#l83
https://sourceforge.net/p/toolshed/code/ci/default/tree/libdecb/libdecbopen.c#l489

It looks like something like this is meant to work (don't know how
well it works):
 decb copy a_file an_image,:5+0x5A000
(for HDBDOS "partition" number 5)
The destination above is probably a file system, don't know if it can
write to the "raw partition".
