Hello,

Sorry to disappoint you, but at this time, we don't have any built-in solution to achieve this.

Right now, we can only write each Conditional Formatting rule one by one, and only to one column at a time.

We also don't have a way for one conditional formatting rule to 'look' between multiple columns - it can only look through the cells inside its own column, if that makes sense.

You can suggest it to our developers, though - they will do their best to make a solution in the future.

Please feel free to search on our suggestions page, 

 to see if someone may be already suggested this feature. If you can't see it, feel free to add your suggestion there,  and as more people vote, the feature will move higher on the priority list.

You can certainly follow our changeLog page if you'd like ( it is also available in the plugin dashboard), where we state any changes/new features/bug fixes during updates;

and our newsletter, so you're informed about new features, bug fixes, freebies, etc.

If you have coding skills and wish to try to make a custom solution now,

you can check out our available hooks for Developers on this documentation and see if you can find any hook that might help.

We also added this new developer's handbook, which can allow users with coding skills to make custom add-ons.

Our developers will keep adding more custom hooks/examples there over time.

-

Please be advised that custom solutions with hooks are not included in our support.

You can also research resources such as Stack Overflow to see if any other user perhaps found a workaround.

( We do like to give examples for certain solutions, but for this use-case, we, unfortunately, don't have anything yet)
