Move many clips to one track

Is there a way to move all my clips in a Montage that are on multiple tracks, to one track lined up one after the other?

No, but I guess the quickest way is to do it from the Clip Tool Window:

thats almost a good solution, the next question is, can I select all the clips in the clip window and change the track one time?

No, sorry.

thanks for you input as always PG
