[Feature]: Advanced model loader

[IowaSovereign]

Feature description

For users who would like greater control over the components of the model or would like to assemble their own using individual components, an additional, more advanced model loader could be useful. As Vlado would like to preserve the current model loader as is, it could be a subtab of the model tab.

While the above is doable using the current loader it's a little bit clunky, and the advanced loader could serve to enhance the user experience and make it more graceful.
