If Timers are not part of Tools (Press the Remote Icon on the system page for 2-3 seconds to get to the Tools Menu), you are screwed. To my knowledge, there is no way currently available to edit timers in the software You must create your timers on the remote, upload the PCF to Wizz.it, and save. The timer information is in the XML file embedded in the PCF for the TSU7000 so presumably, if timers are indeed available, they will be preserved in the 5400 PCF file upon upload as well.
