I am working with tags for nearly 20 years if not longer. So imagine that I created a tag for every country neccessary, and then each country has 10 - 150 child tags.

During the years the number of countries was growing and I would like to move several countries to a parent tag for the continent - but I can't find that this is possible?

So far I did it with some countries (with only a gew child profiles) that I created the country-tag new as a child of a continent-tag, but also had to create all the childs of the country. And then untagging all the "old" childs of the country alone and tagging each profile new with the country as continental child.

This is hell of a job and a huge danger to do something wrong. Now there are remaining countries with 100 and more child tags, so the work would cause countless hours.

Is there a chance to say: Okay, this group of tags (with all child tags) is now a childtag itself for this NEW tag?

It looks like drag-and-drop works in the Edit Tags window. So if you create Continent tags you might be able to drag the Country tags there and thus make them child tags. You might want to create a small test database to try this out on, to see if it works the way you want it to.

I see that Marty beat me to this.
