Close all positions in 1 click on the screen

Hello
I close my positions with total net winnings.
Each cbot or each indicator or instance is connected to a label..and total earnings individually and automatically closes each of them.
As if below, I visualize on the screen my operations .....
But if for one reason or another I want to take my profits or losses on a single instance (which can be composed of several open trades) I am obliged to cancel them one after the other on the screen or on the board .
Is it possible to add a code that allows to manually close all positions (by label) in one click on the screen ..? a logo or a cross....etc
Here is a sample code.
thank you very much
