Can't Delete Map IDs

[ColdForest]

I must be missing something: how do I delete *all* the map IDs (context sensitive help folder in the output setup pod) without having to *individually select the ID, press 'remove map ID', and answer 'Yes' to 'are you sure...' dialog*. I know this must be possible otherwise the thousands of map IDs I have will take hours to delete manually (way faster to just re-create the entire project from scratch). I want to re-generate (via automap) after changing the starting number of prefix...

I'm working with RH2019 *Classic* (since non-classic is incredibly broken) and I'm sure I was able to do this in both RH2015/RH2017 by selecting all of the map IDs and then deleting (and only answering 'yes' to the 'are you sure...' prompt once ).

Thanks in advance.

Finally found this: the only way to do this is to *remove all the topics*. Once removed the map IDs also disappear. Would be nice to have a way to just re-do the auto-mapping without having to go through the topic deletion/re-import (Word) document sequence...
