Password reset message – change the network_home_url( ‘/’ )

I would like to change the usual message sent by WordPress which says the following:

Someone requested that the password be reset for the following account:
http://myexample.com/

I know that this comes from wp-login.php which has the following lines:

$message = __('Someone requested that the password be reset for the following account:') . "rnrn";
$message .= network_home_url( '/' ) . "rnrn";

Is there any way I can change $message .= network_home_url( ‘/’ ) to
http://myexample.com/member by adding something in functions.php perhaps?

Many thanks.
