Does anyone know how to do a tempo change in the Zoom r24?

I bought a zoom r24 recorder recently. Im planning on recording mostly heavy metal bands as well as my own music with it.
There are a lot of tempo changes withing each of the songs and i was wondering if there was any way to make a tempo grid in the r24?
 
I can set the metronome and tempo but I dont know how to add a time change on a particular measure and have it change automatically while recording.
I have searched and searched but no one seems to have asked this question and it is important for my projects.
Itll make it easier to work with inside of sonar if the project is already played to a click track with the tempo changes as opposed to make the changes in sonar and audiosnapping it to time (that never seems to work right for me)
 
Thanks
Miguel
