Geostates for custom content?

[cakeefeatured]

I was wondering since everyone is making custom content of various heights and shapes, how will the objects appear correctly onto these objects we have created? Will they have Geostates like sims 4 has where their editor for TSRworkshop for making custom content, allows you to redefine the data so say for instance a shelf allows things to appear or reappear on/in it.
