Multivote plugin doesn't separate the names

From https://addons-tngtech.atlassian.net/browse/IP-32
The Multivote plugin (https://marketplace.atlassian.com/plugins/com.tngtech.confluence.plugin.multivote) has an issue where the CSV Export does not separate the people names with a semicolon, using instead a comma. How can this be corrected so that the export is useable for reporting? Or is there a better way to track purposeful acknowledgement (a manual acknowledgement vs a log of everyone who has viewed the page)?

Export Example:
"If required by your supervisor, please check the box to acknowledge that you have viewed this document..";"2";"Roberts, Daniel, Lomba, Eric"

The comma after Daniel should be a semicolon. Or even better would be to return a list of unformatted usernames, to display for example “e0167959” instead of “Daniel Roberts”. We could then export the list of employee numbers and query our LDAP for the employee IDs.
