What is the process for making changes like adding track chairs? I know there are impacts on conference logistics (like when tracks are decided upon). Track chairs seem like a popular idea and one that has been used successfully at other conferences. Can someone share what the process would look like to make a change like this?

Note, I am aware that announcements are coming to share coming changes. At the moment I’m curious of the process, and am using track chairs as an example, of how changes are made.
