It will be helpful to have the option not to inherit all custom fields for the space into a new list. Or at least to be able to turn it off on the list without removing them.

Eg. I have some customer fields pinned to my taste at the sprint folder, but I need to have a totally different set of custom fields on my vendor list. These two sets of custom fields never cross each other. For now, the only way to do it is to create a different space, which is not optimal
