Bash command to archive nested directories into individual archives

I need someone to figure out the syntax for a bash command that will run in the Mac OS X Terminal and execute the keka7z program to archive the files within the current directory tree into individual archives, one archive per subdirectory, while preserving the original directory structure.

An example directory tree:

\file1

\file2

\file3

\directory1\file4

\directory1\file5

\directory1\directory2\file6

\directory1\directory2\file7

\directory1\directory3\file8

\directory4\file9

\directory4\file10

Running the command in this directory would produce five total 7z archives:

root.7z (containing file1 file2 file3 with no path)

directory1.7z (containing file4 file5 with path \directory1)

directory1_directory2.7z (containing file6 file7 with path \directory1\directory2)

directory1_directory3.7z (containing file8 with path \directory1\directory3)

directory4.7z (containing file9 file10 with path \directory4)

This command should archive only the files found in each directory into each unique archive file. Extracting all five archives in the above example would yield the original directory structure. Empty directories would be ignored (not create empty 7z archives).

The command should also include the command line options to use "Store" compression (-mx0) and volume segmenting of 4480MB (-v4480m) and stop or warn the user if it attempts to overwrite any existing files (for example if there is already a root.7z etc).

The path to the keka7z executable on my system is

/Applications/[login to view URL]

If there is a way to automate this further or make it easier to use I would be open to additional milestones once the basic function is accomplished.
