Hi all,
I'm new to Power Apps, I'm currently developing a Production Planning Application. I am using Sharepoint Lists as databases for the information entered to be stored. I have a list for each process, Kits & Dispatch Plan. All these lists will be edited in the application.

I'm using a gallery with labels & text inputs as the table of entry.

My questions:
1. How can I generate a column for every new day, for example when the planner selects Create New, a new column is added to the list, with the name of that day, & the forms then update accordingly.
2. If they want to view previous plans, how to I refer back to the column of that specific day? It would be good if they can do it via the Date Selector.
I've tried a whole lot of things but have had no success.
Thanks in advance!
