Connecting a calendar with appointments and deadlines to excel

Hi everybody!

I would like to connect a calendar to excel (or make a calendar in excel), so that I can recieve notifications when appointments and due times are closing in.
The due times and appointments comes from different categories, and one category may include several appointments. I would like to get the notifications in the same
cell for each category, so that when one due time is passed, it automatically jumps on to the next deadline.
Is this something that can be done?

Attached is a sheet where you put in one deal(category) in each row, what I want is the recurring deadline cells to consecutively count down to the recurring deadlines.

Hope someone can help me out!

I have a hard time getting any replies on this forum. Does my post porly describe the problem?
