How can I overcome the object limitations in each room

So I have levels where there are over 1096+ objects in it and for some reason when adding more after 1096, the said later objects won't be seen in game. I know this is due to the engine limited memory usage for each level but is there a way I can be able to keep my original level without removing anymore active objects, all while trying to keep the memory usage at low so I can add more objects later on?

I think the best way of solving this is to just not load any objects unless it is shown on screen, and just show a certain amount on screen, but I don't know how to do that...

in your frame properties you can set the object limit, up to 20,000

Thanks a lot!
