Is there a way to merge columns in discover view to occupy less horizontal space?

I have a case when a lot of data is spread horizontally and can be just reduced if combined in one column.
For ex:

Any thoughts on how data could be shown with less white spaces in the discover view? The keywords PASS/IN_PROGRESS/... could be reduced to just an identifying character.
I am using discover view in a dashboard.

It would be very nice to have feature to add data to an existing column rather than new column for it.

The only way I can think to do this is with a scripted field to join these fields together into a single one. That is, unless you're able to reindex your data to combine these fields into a single property at the index level.

I managed to do this

image

using Scripted field -> URL -> Image where an string array could be provided.

But it would have been nice to have a tooltip on hover for the list item. Or an additional field should take what to show on hover over image. It's a Url of type image, but it's not pointing to any link either, just shows an image.
