NOTE: Make sure you have spec sheets attached to your items first. To learn how to do that, click here.
Go to Designer and click +Add Page. Then click Spec Sheets, name it, and hit Add.
Now that you have a Spec Sheet page in your list of Company Pages, you can add this page to your Report Group.
To do this, go to the Report Groups section within the Designer, and selec the report group you'd like to use (or create a new report group.)
You can then drag your Spec Sheet page into that report group, and your changes will automatically be saved.
Now when you create a report using that report group, your spec sheets will be included.
Please feel free to ping us on the chat if you have any questions about this!
