Save options for subfolders only?

In a folder, how can i apply a certain set of columns to all the subfolders only? So, the main folder would have different columns than all the other folders below, being hundreds of them.

What i have tried so far, was changing the main folder to what i want to have in the subfolders, applying it, then changing back the main folder to what it initially had been. Isn't there maybe a more elegant way?

Use a wildcard path format. E.g. if you want all subfolders below C:\Moo, the wildcard would be C:\Moo\*

Oh, of course. Now i remember again. That wildcard path even existed already, i only have to update it now. Thanks!
