There is a way to create a quote line text field. To do that, you should go to the quote. Then add the products that you need to add or edit the lines. Then add the product and click select. Next, go to the tab that is labeled standard. Open up the quote line. Then select a picklist value. Click done when you are finished. Last, press into the text field.
If the Universal Containers company has a custom Quote Line picklist called Process, then the user will need to set this field for all non-subscription products that have been added to the Quote Line Editor. To do this, the Admin must customize the layout of the Quote Line Editor by editing the line Editor field set on the Quote Line object and drag in the process field.
