Hello Experts,
We have a very unique requirement, please help me to achieve it.In taskspace form plain actions we have options to set input parameters and get back output parameters like in the following image.

But for other actions the same functionality is not available. For example for initiate process form this options are not available.

What I plan to do is when a user receives a task they can respond it by clicking on respond button. When they click on response button it initiates a new process. What I want to do as the user starts new process the initiate process form should return true or false back to previous form from where it was initiated. If they click on finish the value should be true indicating that a new process has started, otherwise the value will be false.Based on the value true/false I will disable and enable some controls on the task form. Please help me to achieve this.
Thanks in advance
