There should be a way to select which Flatshot view is generated for the assembly and shipping reports, and/or an ability to inject your own image - per product.
I know that the report editor allows you to present a few views, but they are fixed by the report. In our case, 9 times out of 10 with custom products, the standard front view set on our assembly report needs to be removed and replaced with a PDF editor like Bluebeam, when the system might otherwise be able to generate a view that could be useful.
I suggest including a drop down box within the "Flatshot Instructions" subassembly with various options. Bonus points for a preview within the Prompts window.
