I'm trying to save a group of objects in game as it's own seperate sprite or object and i'm not sure if there's a way to do it or not.
What do you mean by save the object, what are you trying to do?

You can create a 'Family' of group of objects (sprites) in Construct. An Event/action on such 'Family' will be applied to all the objects within it.
Look into: https://www.construct.net/en/tutorials/introduction-families-56
or a Container.
I agree, the question is to vague, you need to explain what you are trying to do.
