Can I update Samsung's Calendar

[flybub]

Hey everyone. I love this tablet and I also just got an S7 Edge, however, the stock calendars are different. The Samsung calendar on my tablet will not show tasks that I made through the stock calendar app on my phone, but will show events. Is it possible to update the calendar on my tablet or am I out of luck? I really do like the stock calendar and do not want to change if at all possible. Thanks
