Permanent replacement pairs

Hi everyone

I know I can store a replacement pair with aspell_speller_store_repl(), 
but (as far as I know) this is stored in the memory of the running program.

Does aspell come with a way to store "preferred replacements" 
permanently in files?

Thanks in advance.

PS=I use the aspell C API but I understand that both C and command-line 
funcionalities are exactly the same.
