No, only groups/meetings can submit a ballot response. However, individual members can submit their vote by voting in the group conscience business meetings about this motion for the groups/meetings they attend. So while individuals cannot submit a ballot vote, there are many opportunities for individual members to vote in the different meetings/groups that they attend.
This demonstrates the importance of providing sufficient notice to the meeting/group of when the group conscience business meeting when the motion will be discussed and voted on is scheduled. While a minimum of two weeks notice is typical, since there are six months for voting to take place, it is possible to provide even more than two weeks notice if there is any doubt that some members may not have been adequately notified of when the meeting/group’s business meeting, discussion and group conscience vote will occur.
However they decide to proceed within their autonomy provided by the Fourth Tradition, meetings and groups should ensure that their group conscience business meetings do not happen on a whim so that all members who wish to have an opportunity to participate in the discussion and voting process.
