Option to copy all articles with/without collections to a new or different help center

Based on different product combinations that we offer, we need to be able to copy multiple or all articles based on their collection to a new or any existing help center. We used Adobe Robohelp for documentation earlier which worked locally and had this feature which made it really easy to create new projects with similar content with small changes.
With Intercom, it is really difficult to copy individual articles. The size of images often change to their default size (instead of the size of the image in the article from which it was copied) when we copy any article content and we need to change it manually everytime. Also, we need to change all the links manually as per the new custom domain that we would configure for the new help center. We have a huge number of articles in our primary help center and it takes a lot of time to copy them one by one and customize each of them based on our needs.
