setting custom to cost estimate type

AI generated answer (using internal Slack threads):

Based on the conversations, it appears that the default Cost Estimate Type in Items cannot be set to 'Custom' directly on the item itself. This option is only available on transaction line items. If you don't see it on sales order or similar, you may need to customize the form. However, it's important to note that you can't actually change this default from 'Average Cost'. Your options are to use a Workflow, a periodic mass update, or a CSV import.
