Hey 92frazerrrr , welcome to our forum! The ability to edit our assets has been requested before so this has been filed as a dedicated feature request on our agenda. 
I'll add your feedback and a further +1 through your voice to the topic. Currently, our assets can not be edited (besides scaling, moving, rotating), but this may be possible in the future.
Hi Demian Gutberlet - just wondering, as your response and the original question were posted 2 years ago, if it's possible to edit assets now? I would like to do exactly what 92frazerrrr was asking about and be able to edit the pictures within the picture frames so it isn't just a repeat of the same picture.
Metrical2021 , I'm afraid not - I have gladly forwarded your feedback as well but for now, this is not something that is planned to be added soon - be aware that you can also always import your own models as custom assets into our library. This would also allow you to create multiple versions with slightly different styles, just not with our existing assets yet.
