I have a csv file the contains a date and a value

```
Date, Value
2020-03-18,90.0
.
.
2020-04-10,100.0

```

I am loading this file using read csv and applying a function to the date to convert it to a Quantlib date.

```
pd.read_csv(file_location,header=0,float_precision='round_trip', converters = {'Date': DateList.ql_date_from_str})

```

this gives

```
                    Date  Value
0       March 18th, 2020  90.0
.
.
20      April 10th, 2020  100.0

```

Is there a quick way that, as well as having the Quantlib date I can set the index to be the date during the load?

e.g.

```
                        Date    Value
2020-03-18    March 18th, 2020  90.0
    .
    .
2020-04-10    April 10th, 2020  100.0

```
