Set a standard set of fields for updating to catalog

In System Integrator you have the function to update your products from the project you’re working in to the catalog. So if you for example updated the I/O’s or other specifications, you can update it to the catalog. However, we use quite a few custom fields, where there are a lot of Project specific. For example: Hostname, Masking Field 1&2, Gateway, etc. You don’t want those specific fields filled in your catalog. When you update a product to the catalog, standard every box is ticked. I want to create a specific set of fields you can update to the catalog.
