Probably it was already suggested, but didn't find anything.
When adding multiple people as show cast/crew or episode guests cast/crew and the "Return to this page after a successful create" checkbox is flagged, it could be useful if the last entered options were kept as default value in the new page.
For example, when entering guest stars, if the previous entry had the "Voice only" checkbox flagged, the new page could keep the same flag (this would be amazing for animated shows); or, when entering guest crew, if the previous one was entered as Executive Producer, the new page would load the same value as default.
Thanks!
