Tradingview indicator

I need a tradingview indicator that can look at lines plotted on the chart and redraw them up to a certain date, so lets say i have a line drawn from A to B and the half way point is C or any date i can put there, the indicator would get the lines and cut them off at the specified date but retain the angle of all the trendlines. Indicator would just shorten trendlines and make them not date back so far.

in the photo attached, I need a indicator that will see the trendlines drawn, I select a date for it to cut off at and it will cut off at the blue arrow and retain the angle of the trendline. so it will redraw the ray a the blue and retain the angle.
