How to loop audio track and how to replace audio tracks.

Hello. I am using premiere pro cs6 win version.

I have two noob questions.


Can I loop audio tracks like After Effects in Premiere Pro? AE can loop audio tracks by using simple expressions.

For example I have a audio track whose duration is 10 sec and I want to loop it and make the total duration 1 min.


And can I replace audio tracks at once?  In AE, I can replace layers with other footages at once, if I hold alt and click footages from project panel and drop them onto layers in timeline. I mean I placed 100 same “sound effects A”(0.1 second)  in audio track 1, and I want to replace all “sound effects A” with “sound effects B” at once. Do you know how?


Thank you in advance.
