'Check in As' multiple topics

Hi All, I am pretty new to Arbortext and I am facing a problem. I have a couple of projects under a root folder and each project has multiple topics. I created a new project and I wanted to 'Check in As' the topics from the projects to the new project. However, it has really become a tedious task as I have to manually 'check in as' each topic one by one. Is there any way I can manually 'check in as' multiple topics at the same time?

What I am currently doing is that I first view the topic and then use the option SDL Live Content > Check in As.

Any help would be hugely appreciated.

Thanks in advance.
