AFAIK from the appian runtime environment you can delete the latest version of objects one by one. It is tedious and is not a very efficient way to revert back but I know of this one. For process models, rules, constants-all of them you can do this to revert back to last versions.

If you have a old version of the patch, import it to reflect to the old code and delete any new objects.

As many have pointed out, there is no easy way to do this. You options are to revert each object to it's previous version (which IIRC, some objects don't have version history exposed), ask Appian Cloud to revert to a previous back up, or flash your on premise to a previous backup. If this is a risk you find you face often, I would suggest to build a "Reversion Export" application to include all the objects for deployment in your target environment before importing your new app. In this way, you only need to re-import the objects with the reversion app to revert back to before the import. 
 Also consider using GIT or SVN to save all your export zips. In this way you can easily find the previous import to revert. Of coarse the issue here is that you may need to go several imports back, to find the correct objects you want to revert, and they may be coupled with other objects you do not need to revert.
