Is your feature request related to a problem? Please describe.

• Several com_content categories with 3000 articles or so exist.
• 75 articles or so should be moved from one category to another and get a tag.
• I had a long unordered paper list with ids.
• I opened the backend view com_content->articles and set the filters.
• Afterwards checked all ids in com_content->articles view. Scroll up, scroll down, click, scroll up, click and so on. Check what you have done and if it's correct.
• Started a batch process: Move to category xy + Add tag yz.
• And get an message

Batch process failed with following error: Another Article in this category has the same alias.

• Some articles have been moved others not.

Describe the solution you'd like

• The batch process doesn't stop the whole queue somewhere in betwwen (where?) and doesn't move some articles that don't have alias conflicts.
  and/or
• An info which articles have the same alias. Which one haven't been moved.
  and/or
• Move conflicting articles with a new alias (numbered one or easy to find one per filter?) and mention that.
  and/or
• All articles have still their checks after page reload.
