C++ Plugin: How do you enable Nanite & add collision

I’m trying to simplify my workflow of creating voxel art through MagicaVoxel and importing into Unreal.

I’m using the VOX4U plugin by mik14a (awesome plugin for this, props to him). I modified the code and rebuilt it so that I can edit the scale each time (he disabled due to issues with 5.0; enabling Nanite seems to fix this for me), but also changed the default so my setup will automatically be scaled the way I want (32 voxels per 1 meter; so 3.125 scale). This makes it as simple as drag & dropping and clicking import…

Except that each thing I import I find myself manually enabling Nanite and adding a box simplified collision. Are these actions that I can program into this/any plugin? I’ve tried searching the docs but I’m a very inexperienced programmer and haven’t been able to find anything I can understand. Any and all help appreciated, thank you!
