You should be able to append on every server. If the file doesn't exist, it will create it. You really then only need to be sure of setting the permissions correctly for the key to be considered as secure and allow the various commands to work.

ssh-import-id

ssh-import-id(1)						    ssh-import							  ssh-import-id(1)

NAME

       ssh-import-id  -  retrieve one or more public keys from a public keyserver (Launchpad.net by default) and append them to the current user's
       authorized_keys file (or some other specified file)

SYNOPSIS

       ssh-import-id [options] USER_ID_1 [USER_ID_2] ... [USER_ID_n]

OPTIONS

	-h | --help	   usage
	-o | --output F    write output to file 'F' (default ~/.ssh/authorized_keys, use "-" for standard out)

DESCRIPTION

       This utility will securely contact a public keyserver (https://launchpad.net by default) and retrieve one or more user's public	keys,  and
       append these to the current user's ~/.ssh/authorized_keys file.

       The  system  administrator  can	change	the source URL used by ssh-import-id(1) by editing the configuration file, /etc/ssh/ssh_import_id,
       which is sourced to obtain the value of URL.  By default, URL="https://launchpad.net/~%s/+sshkeys".  Note that this url really  MUST  be  a
       secure,	https  url with a valid, signed certificate or else your system will be vulnerable to man-in-the-middle attacks!  The "%s" will be
       populated by ssh-import-id(1) with the value(s) of USER_ID_1 [USER_ID_2] ... [USER_ID_n].
