[Bug report] Enable quick toggling of sub-tag/sub-studio content

[itanameiguess]

Is your feature request related to a problem? Please describe.
When using studio/tag hierarchies there may be many levels of parent tags/studios. Previously it was relatively easy to open the pre-applied filter and toggle inclusion of sub-content, now a new filter must be applied to include content you are looking at then toggled

Describe the solution you'd like
Add an option to toggle inclusion of sub-tag/sub-studio content when viewing any tag/studio which is a parent. Default setting is available as an option already but changing views can be desired

Describe alternatives you've considered
Returning previous behavior changed by 4705 as plugin/settings toggle

Additional context
Behavior changed due to #4705 with v26.0

Marking this as a bug because it is a regression of previous behaviour.
