usernames when insert hash list ?

[__KiNG]

hi,
for example i have a big list in format :

USERNAME:HASH

i need to clear all usernames first and insert only my big HASH file.
after cracking i need to manually find username for the cracked hashs

so my be something to put the hash file in format :

USERNAME:HASH
and getting result in format :
USERNAME:HASH:CRACKED HASH
or
USERNAME:HASH

just an idea but personally for me it will be really perfect
thanks and peace
