You would have to put in the password first to create the hash. Then you could script out the hashed password to the rest of the devices. You also have to use the password secret method.
Cisco type 7 encryption uses a weak non-consistent hash method that will result in mismatches among devices using the same base "password" but with different resulting hashes in their configurations.
This can be verified by the existence of password hashes preceded by the number "7".
Example:
username jdoe password 7 07362E590E1B1C041B1E124C0A2F2E206832752E1A01134D
Cisco documentation recommends that all customers switch to the password "secret" method will utilizes md5 hash method and can be verified by configuration lines with a hash preceded by the number "5".
Example:
enable secret 5 $1$iUjJ$cDZ03KKGh7mHfX2RSbDqP.
