  Hi

  I’m trying to implement the undo/redo like i saw in the documentation:
  
  https://www.grapecity.com/spreadjs/docs/features/worksheet/undo

  In your documentation example, for setting commands in the same undo/redo transaction i need to put them between “commands.startTransaction(context, options);” and “commands.endTransaction(context, options);”

  in our system we have async flows, it means that i want to insert commands from before the async call and after it returns to the same transaction .

  For example, i may want to put commands into transaction A through an async call, and while waiting for the call back add commands to transaction B in a different flow, when the async call return i want to add more commands to transaction A.

  is it possible?

  const cell : GC.Spread.Sheets.CellRange;
  const cell2 : GC.Spread.Sheets.CellRange;
  ): void {
  	const command = {
  		canUndo: true,
  		execute: (context: GC.Spread.Sheets.Workbook, options: any, isUndo: boolean) => {
  			const commands = gcModule.Spread.Sheets.Commands;
  			if (isUndo) {
  				commands.undoTransaction(context, options);
  				return true;
  			} else {
  				commands.startTransaction(context, options);
  
  				cell.value("value")
  				setTimeout(() => {
  					cell2.value("value2")
  				}, 200)
  
  				commands.endTransaction(context, options);
  				return true;
  			}
  		},
  	};
  	const commandManager = gcModule.workbook.commandManager();
  	commandManager.register("id", command);
  	commandManager.execute({ cmd: "id", sheetName });

  Thanks
