Is there a way to simulate "Continue where you left off" function?

My use case before discovering this plug-in: I turn on "Continue where you left off" and I keep around one single window that slowly accumulates more tabs. I know this causes problems with TO, so I turned off that option. What I want to do is essentially maintain the same work flow except being able to save pages into the tree so that it doesn't get as clustered. To replicate that, when closing I need to 1. close and saving window in TO 2. close TO itself and when opening chrome I need to 1. open chrome 2. close new empty window 3. reopen window from TO. Is there a way to click one single button (or preferably one key combination) that closes TO *along* with currently opened windows and next time chrome opens have it automatically reopen the last closed windows (basically condense the actions needed)?
