I'm trialling Gantter to see if it would be a useful tool for managing our Senior Management Team's work plan. There are multiple work streams which are easy enough to manage as conventional projects, but I need to identify which monthly SMT meetings each work stream is expected to report e.g. Finance in Feb, Apr, Jun; HR in Mar, Jul, Sept etc. I wanted to show the meeting dates as milestones on a single line in the Gantt chart, is this possible in Gantter?
