Course Estimated Total Time

Hi all,

I seem to be unable to find an IQ datafield app that would display the estimated total time (ETT) for currently loaded course. I can display Distance Remaining, Estimated Total Distance, ETA (Estimated Time of Arrival) and ETE (Estimated Time Remaining). What I would like to see is something like

ETT = Timer + ETE

or

ETT = ( Timer / Distance ) * Course_total_distance

Is there such app in the store? Thank you.
