You do not have to enter all 50 parameters. 
If editing existing task, only enter modified parameters. 
If adding new task, enter all required parameters.
Task.TASK_TITLE and Task.TASK_TYPE are required parameters.
Look at the task property files in the 'data\tasks' folder to see the parameters for each task type.

Also see addprop function which allows you to change a single parameter in a task, schedule or settings file.
