php - How to get columns in Import/Export Member CSVs to match in Silverstripe? -

i have silverstripe project additional fields added fellow member object via dataextension:

class clubmemberfields extends dataextension { private static $db = array( 'membershipexpireson' => 'date' );

if go security > users in cms next message under "import users" > "advanced usage":

allowed columns: firstname, surname, email, password, rememberlogintoken, numvisit, lastvisited, autologinhash, autologinexpired, passwordencryption, salt, passwordexpiry, lockedoutuntil, locale, failedlogincount, dateformat, timeformat, membershipexpireson, validationkey, needsvalidation, needsapproval, publicfieldsraw

which because want import users "membershipexpireson" field.

however when select export csv returns next columns: firstname, surname, email

how create exports "membershipexpireson" field csv?

any additional summary fields exported csv:

class clubmemberfields extends dataextension { private static $db = array( 'membershipexpireson' => 'date' ); public static $summary_fields = array( 'membershipexpireson' );
