need advise on creating and adding to a list and save it

Hi for personal use i would like to create a little thing to have on my phone to keep track of the hours i work. I have a scene where i add the hours daily, the scene is a week. ![alt text][1] [1]: /storage/temp/190767-week.png

Now, I have in mind to create another scene where I ask my self if i want to add a new week and visualized a list of the weeks i have already done.

the script for the week input is working ok , but i do not know how to approach the scene I am telling you about

i see i can use input field when i ask which week would you add , and have an integer for that, so i assume i can create a list called weeks of integers and that's it

but once i input the week number what would be the process to have the scene with the weekdays and fill them up ?

I am a bit lost on that thank you

here is the code for the weekdays in case someone wants to use it , i am adding or removing half hour each click of the buttons

  private Dictionary<string, float> myWeek = new Dictionary<string, float>();
     public Text monday;
     public Text tuesday;
     public Text wednesday;
     public Text thursday;
