Is there a way to know if an item has already been used in other projects?

Hi, there! My client does not want to use an asset that has already been used in another project. And I am having a hard time remembering every asset I have used for him or other clients.

Therefore, I would like to know if it is possible to know in which other projects a certain element has already been used.

I am grateful that envato now allows searching by “projects”, but it’s not very useful if I have a huge list of items in a project.

I hope you can give me some suggestions or workarounds for my problem. Thank you for any help you can offer me.
