Loading multiple data files at once in power bi template

Hi, All,

I've created a report using 2 source data and this report will be shared among others. For this I created a parameter with current value as my source data location as shown in the picure below then created the template. This created template works fine but loads only single data file. My data folder has 10 csv data files and I want to load them all at once in my template. Thank you!
