A custom implementation for this is possible, and can be done as follows:
``` python
# Rename columns to be unique
informative.columns = [f"{col}_{inf_tf}" for col in informative.columns]
# Assuming inf_tf = '1d' - then the columns will now be:
# date_1d, open_1d, high_1d, low_1d, close_1d, rsi_1d
# Shift date by 1 candle
# This is necessary since the data is always the "open date"
