1) Add a Timer element. Initially Disabled. Specify the Maximum Events = 1 and the Time Offset as a variable (or the constant time if that is the situation).
2) In the process with the Wait step, right before the Wait, assign the Enabled state of the Timer to True to start it up.
3) In the Wait step, wait for either your primary event, or the Timer event, whichever occurs first.
No need for a second process. Just a combination of a Timer and a Wait step, with the Timer's event being one of the possible events that the Token may be waiting for.
