Can the user create new entities ?

Members of this group,

I know there have been posts about entities and how to create them. Looking at the documentation, Entity can be specified as Entity[“Type”,name]. To me it seemed that this could be constructor. In some experiments I have type

Entity["PowerConverter","Boost"]

But nothing really happens!

Is that possibility really close to us?
I would like to define power converters such as the buck converter, boost converter, etc. as entities within property values such circuit diagram, circuits graph, state space model, linearise model, etc.
Is this possible via entities??

I will appreciate any comment.

The answer, I believe, is no. Read the following thread for some insight:

What a shame!. It seems such as nice idea.

Thanks
