No, there is no longer an option to indicate this within the symposium submission. However, because we allow one symposium submission AND one single presenter submission, the individual presenters have the option to also submit their presentation separately as a single presenter submission. An individual can only present once as a main presenting author in the Science submissions, and if the group submission is accepted, the single presenter submission will be declined. The "Plan b" option still exists; it just requires that the talk is submitted separately as a single presenter submission. This also allows for the option to submit a different talk for consideration than the one submitted in the group submission.
