Hi Edon, yes it's actually possible to install an extension right now that will give you an object library pretty much just like you're describing.

See Mik's link above for a recent video tutorial from Chipp that covers this exact topic.

And the extension is the Object library from Max Smirnov which is here:

That should give you a library function pretty much just like you’re describing.

Thanks, - Michael
