Minecraft For ps4 advice?

I'm playing Minecraft on my PlayStation and I built this really cool aquarium and zoo and whenever I go to work on something else, all the animals despawn and it sucks that every 10 minutes I have to replace them (creative mode) is there any way I can make it so they just stay put?

Not sure if it's the same for console versions but on PC, entities that have been named with a name tag won't despawn.

Use a name tag and name all the animals
