How to Generate ID Count Per CSV File Upload

I am trying to generate an ID via count of iteration per row in the CSV File that I will be uploading.

Example, when I upload CSV with 100 rows I am expecting data-1, data-2, data-3, … data-100. This can be done easily with SimpleLooper Current Iteration Number. The problem is when I upload a CSV File again, the SimpleLooper Iteration will reset to 1. What I want is to continue the iteration so data-101, data-102, etc. This is only within the day, so in the next day I want the iteration to reset to 1.

how are you uploading the CSV?
