Suppress articles listed in Spotlight from the Feature Articles section

Suppress articles listed in Spotlight from the Feature Articles section
Theme: Newspaper (tagDiv)
Website: https://covertactionmagazine.com

Description:

1. In Edit with tagDiv, I have a Front Page with numerous Flex Bloc 1s.
2. One Flex Bloc is titled Spotlight and shows articles with the Tag:Spotlight
3. Another Flex Bloc is titled Features and shows articles with the Tag:Features
4. I want to be able to show articles in Spotlight, but not have them show up AGAIN in Features, on same Front Page.
5. SOLUTION: Tag articles appropriately with SPOTLIGHT or FEATURE. Sure, but this solution is time consuming to RE-TAG articles all the time, since articles are in the SPOTLIGHT for about a week.
6. DESIRED SOLUTION: 99% of all articles are always tagged FEATURE. Sometimes they are in SPOTLIGHT. For those also tagged SPOTLIGHT, set the FEATURE FLEX BLOC to <<NOT SHOW ANY ARTICLES THAT ARE TAGGED SPOTLIGHT>>. Then, I can rest assured there is not redundancy. And all I have to do is add or remove the SPOTLIGHT tag when alternating articles INTO THE SPOTLIGHT SECTION. The FEATURE section will not also display any articles in the SPOTLIGHT.
7. To do this, there is a feature which I tried to configure, BUT I AM NOT SURE OF THE SYNTAX.

DESCRIPTION OF EFFORT, BUT DID NOT WORK:
1. POST ID FILTER: yes this works, but is time consuming to look up each POST ID…etc.
2. Multiple taxonomies filter: put a “-” before the TAG ID (for SPOTLIGHT)

Among many other things I tried, this obvious one above (solution #2) did not work. I THINK I HAVE THE SYNTAX WRONG, or MULTIPLE TAXONOMIES FILTER does not filter for TAGS. (By the way, I tried both the TAG ID and the word “spotlight.”

Any help is much appreciated.
