Hello dear coders

I need someone to help me customize this vertical line indicator that draw based on the time u set ( basically can be used to draw session open and close ) . I would like it to have below extra features :

1. Option to have 20 vertical lines that can be drawn based on the time you set. ( currently only allow to draw 1 vertical line )
2. Option to customize each vertical line ( option to customize width,color,style of vertical line ) -> [ currently only allow to change the color of line ]
3. Option to write ANY text label next to the vertical line drawn ( example shown in screenshot below : AO -> stands for Asian Open , FO -> stands for Frankfurt Open, FC
-> stands for Frankfurt Close ) & also option to customize the text color
4. Ability for the indicator to draw FUTURE vertical line ( means ability to draw vertical line for the next period also ) & ability for user to select how many future periods vertical line should be drawn ) .. [ currently indicator only draw vertical line when the time set reached, which defeats the purpose of knowing when the session will open to better prepare yourself for session opening]
5. Have one toggle button on/off on chart

A MILLION THANKS IN ADVANCE IF ANY CODERS CAN HELP ME ON THIS ! CHEERS
