When you launch a form in Survey it uses a default “Initial Speadsheet/Worksheet.” You can create a custom Initial Worksheet to control the first screen users see.
There is documentation on changing Survey’s workflow. Here is an example allowing you to skip the saved instances if you supply an “instance ID.” The idea being that no need to select the instance if you already provided it in the intent that launched Survey. The instances selection screen is the default which is called by the default “Initial Spreadsheet/Worksheet”. Instead you can change the opening and finalize workflow by adding a custom “Initial worksheet”.
