Renko Bar Chart Upgrades

I have a couple of requests regarding Renko Bar Charts.

The first is simple - please provide a time/tick countdown for Renko bars. I realize in the historical bars there is no time/tick aspect - they are based on points. But in the current Renko bar, there is a time/tick aspect, before it "rolls", if you will, to the Renko format. Please provide a time/tick countdown for the current Renko bar. Thanks.

The second is likely more complex. Please provide more accurate backtests when using Renko bars. As you likely know, backtests using Renko bars can be wildly optimistic. This request is related to number 1 above - if the current bar is an expanded range bar, it will not transition into a single Renko bar - it could be 2, 3, 4, 5 or more Renko bars. Say it's 4. The backtest will assume your entry is based on the first Renko bar in that series of 4 - but really your entry will happen at the 4th bar. If there was a way to adjust entries and exits for this effect, the backtests would be more accurate, and less optimistic. Thanks.
