I have different set of tables updated on different dates

Table 1

- Location 1, Work Done %, Date A

- Location 2, Work Done %, Date A

I would like to see a report (chart) showing how the Work Done % at each location varies over Date A, B and C.

Instead of using the option "add to the end" (I will get 12 rows of records in one merged table) , can I maintain the 3 files seperately in an online folder and get Zoho Analytics to produce the same report?

What I wish is to achieve: user will add new file every two weeks, to show the updated Work Done % at a new date. Is it possible for Zoho Analytics to pick up the new file and update the Work Done % vs Date report every time a new file is added?
