We need to be able to select our custom metrics LTG and LTC in the retention view (from the drop-down menu) to generate waterfall charts using these metrics. I’d like to be able to see them in the aggregate (e.g., “show me 12-month LTG from June 2025 to May 2026”) and also create custom segments (“Show me LTC for people who purchased XX Protect as their first product in November 2025")
