Input File for Vsource in Cadence Virtuoso

Hi,

I am using vsource component from the analogLib library in my design. I have more than 400 instances of the same in my design & I am using it as a pwl with input given in a csv file. Therefore, I have more than 400 csv files for each of the instances. My question is, is there a way to specify the input file for vsource as a variable? Going over each and every instance of vsource & typing the file name is too cumbersome. Is there a better way I can specify the input CSV files for these sources?

Thanks in advance.
