linear regression v2 mod

would anybody be kind enough to mod this indi so that the linear regressions start at a manually placed vertical line that has 'regression' written in the description? The current method works 90% of the time for placing the regression correctly but those 10% of times when it doesn't are really tricky to dial in, sometimes imposible.

Starting from a vertical line would also enable translation to multiple timeframes much more effectively by modifying the timeframe visualisation for numerous vertical lines.
