Does your product support custom event tracking and server-side setup for WooCommerce + FunnelKit Pro (especially post-purchase upsell events)? Eg, Does it fully support a specific funnel (“purchase_main” + “purchase_upsell” + WooCommerce + FunnelKit post-purchase upsell)? Can it handle upsell events and multi-step funnel logic, not just "standard purchase" only? Thanks!
