That would be an awesome feature! Unfortunately I don't think it's possible. Your best bet is to probably use the v.clean tool from GRASS to automate the fixing of errors. There's a number of cleaning functions available within the v.clean tool such as:
- Break: Breaks lines at each intersection
- snap: Snaps lines to vertex in threshold
- rmdangle: Removes dangles
- rmline: Removes all lines or boundaries of zero length, threshold is ignored
- rmsa: Removes small angles between lines at nodes
Hope this helps.
