How to create the new excel with a different date/fecha while maintaining the checklist, and maintaining the previous date and data that I have saved?

Hello!

I have a set of checklist here. See image 1:

I have created a new excel (image 2) to link the data with the checklist in the image 1, to create a data base for Power BI.

My question here is, is it possible for me to create the new excel (image 2) with a different date/fecha (red arrow in both image) while maintaining the checklist (image 1), and maintaining the previous date and data that I have saved?

For example:

I wanted to create a new checklist for the date 28/02/2022. At the same time, I still wanted to keep the previous data of 25/02/2022.

Do you have any suggestion or advice?

Thanks in advance!
