If my media is 1920x1080 can I create a custom sequence?

Hello,

I currently work on FCPX and want to move to Adobe but before I do I need to know if it will achieve everything I need.

I work with 1920x1080 media but we deliver in many different aspects.  FCPX allows me to create sequences with any aspect.  Can premiere do the same?  Without strectching the media.  For instance we sometimes deliver in 960x544 is this something I could create in Adobe?

Any help would be appreciated.

Thanks
