Is coding this shaded rectangle possible?

  string user_date   = StringSubstr(TimeToStr(TimeCurrent()),0,10);   // today's date
  string user_time_a = "11:00:00";
  string user_time_b = "12:59:59";

  datetime time_1a   = StrToTime(user_date+" 00:00:00");          // day's start time (midnight)
  datetime time_1b   = StrToTime(user_date+" 23:59:59");          // day's end time (one second before midnight)
  datetime time_2a   = StrToTime(user_date+" "+user_time_a);      // start of user time period
  datetime time_2b   = StrToTime(user_date+" "+user_time_b);      // end of user time period
  
  int      bar_2a    = iBarShift(Symbol(),Period(),time_2a);
  int      bar_2b    = iBarShift(Symbol(),Period(),time_2b);
  
  double   highest   = High[iHighest(Symbol(),Period(),MODE_HIGH,bar_2a-bar_2b,bar_2b)];
  double   lowest    = Low[iLowest(Symbol(),Period(),MODE_LOW,bar_2a-bar_2b,bar_2b)];
  
  ObjectDelete("rectangle1");
  ObjectCreate("rectangle1",OBJ_RECTANGLE,0,time_1a,lowest,time_1b,highest);
  ObjectSet("rectangle1",OBJPROP_COLOR,Green);

  ObjectDelete("rectangle2");
  ObjectCreate("rectangle2",OBJ_RECTANGLE,0,time_2a,lowest,time_2b,highest);
  ObjectSet("rectangle2",OBJPROP_COLOR,Red);

I trying to code two rectangles,or let's say box inside box and I managed to draw them in right places but problem is price coordinates for rectangles.Price coordinates for both rectangles need to be same (daily high and daily low) but one box will be drawn from 00:00 to 23:59 and other should be drawn from custom time witch will be entereedd thry input parameters (eg.from 8am to 9am).Problem is second box,because she takes price coordinates (high and low) for time entered and not from whole day.
Here,I'l try to explane thry pictures.
