I don't think there is a "limit-stop-limit" feature on any major exchanges yet.
Binance has it, the limit-stop-limit combination or OCO. However, this feature resulted in 2 orders and this also didn't match OP expectations.
I think the feature that the OP means is on KuCoin. If I remember correctly, the stop limit feature on kucoin can also be set lower than the trigger price. Since Kucoin groups order types between limit and stop-limit, a stop-limit order will become a limit order regardless of the trigger price set.
And a feature that I like about KuCoin is that I can make multiple stop-limit orders on multiple trading pairs with a limit on the amount of each order according to the trading account balance, because the stop-limit on Kucoin doesn't reduce the balance at all before it reaches the trigger price.
