[StashManRon]

(Copy of issue formerly known as #742 - Github have shadow banned me ....)

Is your feature request related to a problem? Please describe.

Currently only possible to filter performers by studio and/or tag.

Describe the solution you'd like

An option to filter by alias assigned to scene

Describe alternatives you've considered

Clicking every scene to see if alias is set/not set is long winded.
