Mass reset beatgrids on Prime 2/Engine DJ

Is it possible to reset all beatgrids on a Prime 2 or in Engine DJ?

Not on OS or Engine DJ… Beatgrid is handled track by track on the units and in Engine DJ

I assume you can easily reanalyse those tracks in order to reset beatgrid. Also the grid must not be locked at this point for these tunes.

All my tracks are reanalysed. I used the edit beatgrid on my prime 2 for the first time last night on a few tracks and it seems to have fixed any beatgrid problems I had for old italian house music.
