Modift Data tables simultaneously

Hi my group me and my group of friends are creating a videogame, and all of our item information is in a data base inside unreal, we are using Plastic SCM as a control source, the problem is that we can’t modify the data base at the same time. So I want to know if there are any actions that we can do so we can modify it, without it being overwritten.

Sorry for my grammar, my English isn’t my native language.

Thanks for any answer in advance.
