Setting Operator travel time along conveyor

In my model, I have made the operator walk along with item in a conveyor using process flow. Operator walks along with item when it reaches a initial Decision point DP1. Now, I want him to walk along the item for certain period of time and return back to initial decision point without setting a final destination Decision point. Can this be done?

I have attached a model for reference. (In the model I have used a decision point for final destination and manipulated walking time by changing speed of operator and conveyor, but I want speed to be constant and distance travelled as variable)

You send a delayed message to the operator. If the operator receives this message, he creates and dispatch a preempting and aborting tasksequence which makes him go back to the decision point. You can achieve the same with a process flow.

@Jörg Vogel Thank you for the reply, can you link me some models, on how to use this delayed message option as I'm new to flexsim.

Hi @Tanuj R, I followed Jörg's great suggestion to make an example of how you might do this. I set a label on the item called "Time" when it's created. I set a 'on continue' trigger on DP1 that sends a message to the operator with a delay of item.Time label. I then add a bit to process flow that has the operator walk towards Queue1 while another token is waiting for the message to be received. When the message comes, it preempts and aborts the previous travel task and comes up with a new one (travel back to DP1 to get the next box).
