Unfortunately I then need to manually add the missing ‘0’s, which can be a huge pain for long listings, and open to human error.

Here is a perl one-liner that does what you want:

perl -n -e 'print join(" ",map(sprintf("%03o",hex($_)),split(" ")))."\n";'

Example:

~[514] perl -n -e 'print join(" ",map(sprintf("%03o",hex($_)),split(" ")))."\n";'
1 2 3 de ad be
001 002 003 336 255 276

I typed the red line as input data, the program output the blue line.
You can also use standard unix file indirection or piping as well on the program 
line.
