Save Sub-Tag Inclusion?

[kgc2k3]

I love how Stash allows for the nesting of tabs, and also how you can alter the filter when viewing a tag to include media from any sub-tags.

However, I was curious if there was a way to make showing media for a sub-tag when viewing the parent a default behavior, either on a per-tag or server basis. This would help speed-up assigning the tags and would allow for easier management.
