There might have been other posts suggesting this feature but couldn't find them.
Which makes me think, may be there is a way to see the tasks from multiple accounts (my personal and my company) in a single My day page. For example I would love to see the flagged emails from both accounts. For now I have move back and forth between accounts to see two different My Day pages composed of flagged mail, planned, task etc.
I found a way through a shared list. My company does not allow me to invite somebody outside of the company but I was able to create a shared list from my personal and invite my company account. Still I believe there could have been a more elegant way combine two accounts of the same person in a single My Day.
