AMO orders for all the stocks in the holdings

Every day before the market opens, I would like to place AMO orders for all the stocks in my holdings. I manage couple of portfolios so i would like to export the holdings in each of the accounts, use formulas like order price below 10% of last closing price, or absolute values and then place orders for all these.
I think there are some zerodha algo trading options but I can’t afford the subscription cost. I buy very small quantities like SIP for long term but I place orders on most of the days. Doing it manual is so inefficient and kite does not offer ‘good till cancelled’ orders.
Any other options, tools ?

No…

As of now there is no other option but we are testing GTC order types so this option should be available soon.
