Display external data in exploration

#1
I have a CSV file with the following columns in order:
Ticker, IVRank, IVPercentile, IV
I want to call this file which is named as "IVRank.csv" and display IVRank and IVPercentile when i run exploration. Please note that the exploration also has other parameters such as Buy/Sell, RSI, etc. Along with these the report should also show the IVRank and IVPercentile which are in the CSV file. Can someone in this forrum help me code this?
Thanks a lot in advance
