How to Retrieve ETF Split / Reverse Split Events (Including Cancellations)?

I am currently working on an ETF data integration project and need to track corporate actions such as forward splits, reverse splits (consolidations), and their scheduled dates for ETFs.

Here’s what I have observed so far:
• Using the RDP Lipper Funds API, I can retrieve historical data on ETF assets, pricing, and characteristics.
• However, future corporate actions (e.g., scheduled splits) are not available via Lipper endpoints.
• Additionally, there is no way to detect events that were announced but later cancelled, which is critical for accurate handling of scheduled data.

My Questions
1. Is there an RDP endpoint that provides corporate action events (forward split, reverse split, CUSIP change) specifically for ETFs?
2. Can we access future-dated events (announced but not yet effective)?
3. Is there a way to capture event cancellations or changes (e.g., scheduled reverse split later withdrawn)?

If no such endpoint is currently available in RDP, I would like to raise this as a feature request. This data is highly relevant for portfolio management systems, backtesting, and ETF analytics.

Thank you!
