Application->Functions->Exists (Waiting too much time)

I use this component to check existence of object.
By existence of object, I decide something in process.

But there is too much time to understand existence of object. How can I decrease this waiting/decision time? For example I want to configure 2 seconds to decide existence of object.

Is it possible to configure it?

There is no field to set the time in the Functions activity.

Is it possible to request to add an item to development future plan?
