I don’t think its possible. Coin is Demat Mode based compare to direct AMC website investment.
Since you have already invested in Direct Mutual Fund mode, why do you want to switch to Coin?
Remember Coin has a monthly fees and Annual AMC charges as well.
If you want to track your investment, check camsonline mailback service to get holding (summary and transaction) on demand
Hope this helps.
Thanks
