Loot underwater crates without untying them?

So i've been trying to make it so you can just open the under water crates without untying them
i've got a few ideas have tried just respawning the crates as totally different crates which works but now i need seperate crate entities for more customizeable loot because those are being used on land

Is there anyway to just turn off the untying on the crate?

Anyone?
