Change timeout value for User Confirmation for Remote Desktop

Hello,

I apologize if this is a newbie question and is answered somewhere else.  I tried various searches on the forum and didn't find the answer.

Is there a way to change the default (60 seconds) that the system waits for the user to confirm before starting a remote desktop session?

I found the setting where it can be turned off/on, but have not been able to find a number of seconds to wait.

Thank you!

Rob
