Make the first author a speaker by default

In the conferences I attend, it’s common for there to be only one author presenting a talk and of course they will be the speaker. Is there any way to configure Indico to automatically select the first listed author as the speaker by default? It is confusing to add yourself as an author but then also have to click the microphone icon to also list yourself as a speaker. Otherwise you get an error saying you need at least one speaker and it’s not intuitive that the submitter has to also click this mic icon:

I know this is a common point of confusion and the indico admins would like this default speaker to be set. Is there a way to do this?
