If two collaborative specifications have been created/shared under separate templates for the same product and they use the same template, you can merge these together to sit under one template. For example see below:
Step 1: From the Collaborative Specs page, click on the menu button beside one of the specification templates that you would like to merge and select Merge Specification.
Step 2: A pop-up window will open with the details of any specifications that have the same product and template. Select the specifications you want to merge and click on Merge. The specifications will now show under the same template header.
*This merge function will join the edit history of both templates for the customer to see but the supplier will still only see the edits made by them*
