Auto-tag leads from a form's service dropdown answer

Let a workflow add a tag (or branch a Conditional Split) based on the answer a lead picks in a form field, e.g. a "Service" dropdown with Power Washing / Window Cleaning / Gutters. Today the tag comes from which form was submitted, so getting per-service nurture messages means building a separate form for every service. Customers want one form where the selected service drives the tag and the personalized follow-up.

Customer quote: "As the customer sees the form, they'll pick a service that they're most interested in, either power washing, window washing, or gutters. And then from there, I'd like the workflow to automatically tag the opportunity with either three of those services... just to get things started, I'll just use a single form for them to pick what they're most interested in."
