Raise object limit in hideout

Haii,
I have spent several hours transforming my canal hideout into a cozy little place with a custom forest and flooring, but with an object limit of 750 and having to place hundreds (350+ grass objects alone) of objects the limit is easily hit and it has been the same ever since 0.1. So I would like to ask if that is something that can be raised? Just increasing it by 250 would mean alot! I would love to be able to extend my forest further over this hideout instead of limiting the size so much :3 Thank you!
