today timing diagram puts each participant in timing diagram (either robust or concise) in its own frame where its name appears in upper left corner. On left appears various states of the participant (in case of robust participant). I would like to be able to specify multiple participants (either concise or robust) under single frame where name of each one appears on left side. For robust participant no state names would appear. For concise participant name of values appears same as today as part of the diagram itself.
