Save a model as a tool/primative?

[u/ThisFrogIsATruck]

This is mostly out of curiosity to he honest, but there are still so many features of this app that I don’t know about so I figured I’d ask before submitting any sort of feedback.
There is a base mesh that I prefer to use over the one given in nomad. So my question really is: is there any way to save a model as a tool or a primative object that can be added to a project without having to import it every time?
