The 2nd condition si currently not possible if you want to enter when any of the following candles after the Supertrend buy trigger crosses the trigger candle. However, if you have a fixed lookback period, it is doable, for example, you want strategy to trigger when the 3rd candle crosses above the trigger candle.
The feature required for this is currently under development and would be available soon.
You can refer to the below thread where a similar condition was shared. You can copy the strategy into your account and make changes to it as per your preference.
