Modified Volume Indicator for Pine Script

The goal of the project is to create a modified volume indicator for Pine Script. The main task is to show after-hours volume in the current daily chart in real-time (which it does not right now) and show pre-market volume in the current daily chart in real-time of the current day (which it does not reflect until regular hours). Please only accept the project if you know this can be done in tradingview. I want the indicator to show 2 more values (relative volume-based values -- which already actually exist in Tradingview).
