Usually visit passes are setup to be sold with a predefined set of themes and languages. However after several months some themes and languages may no longer be available for sales. 

Removing themes and languages from future time slots can already be done in "Visit" space setup. However the process has now been simplified.

Modify future themes/languages directly from the visit pass configuration screen

The improvement implies re-using MODIFY themes/languages option (Visit space - Time slot) on Visit Pass configuration screen (Timeslots menu)
