New Post: "unsuperseded" an update

Hello,

I created a new update for the last flash update (18.0.0.203). I choose to supersed the previous version (17.0.0.188) while creating the package. I shouldn't, because I wan't to test the new update before superseded the previous update.

Is it possible to remove this setting to rollback to the previous status for update 17.0.0.188 ?

Thank you
