Multiple trading account for single demat account

Is it possible to have multiple trading account corresponding to a single demat account with Zerodha?

We limit one demat account to each trading account that gets opened. Is there any specific reason you want to link multiple accounts?

One use case is separation of different kind of holding into different trading account (like short term/long term).

However if we get feature like custom tagging of stocks/holding then, then multiple trading account will not be useful.
In that case you can give user option to set custom tag to specific holding and see holding based on that tag. Effectively Holding dropdown menu will have custom name apart from now available option like All/Kite/small case/Mutual Fund

any update on this? each account can be used for a different purpose, one for trading and another for investing. The investment account is checked on a weekly basis… very less activity
