outputs = [
    "fperiod",
    "esgsourcetitle",
    "esgsourcedate",
    "esgsourcepublisher",
    "esgsourceurl",
    "esgsourceabstract",
]
# Set parameters
params = {

    "EDate": -2,
    "Period": "FY0",
    "Frq": "FY",
    "CH": "Fd",
    "RH": "IN",

metrics = [c + '.' + o for o in outputs for c in controversies]
features = [{m:{'params':params}} for m in metrics

If i make the API call for several companies:

ek.get_data( ['US3696041033','US0378331005'], features)  

I get 5 controversies for ISIN US3696041033, while making the call one-by-one, I get 11
