Enscape Custom Assets Missing

I upgraded to 3.4, and the improvements are amazing! But i noticed some of my older custom assets are not loading. These were custom assets created using the workaround (pre-custom asset editor).

Also, how does enscape link the placeholders to the asset file? Is there a way to change the name of the placeholder to reference the asset package?

Any help would be appreciated.

Thanks!

Looks like when i import packages using the new custom asset editor, it overrides any assets i drag and drop into the asset folder. Is there a way to bach import assetpckg files? It is taking forever to import one at a time.
