Adjustment of TV Specials into TV Series

Hello,

I would like to take 2 pages of content and place them under a TV Series.The first, SPACE Press Event v1 (https://www.imdb.com/title/tt38895469) broadcasted on 12-12-2025, was only slated to be a single episode, but due to the LIVE broadcast success it has been picked up for another episode. As a season expansion, the second episode, SPACE Press Event v1.2 (https://www.imdb.com/title/tt39176387/) broadcasts on 12-30-2025. How can these two episodes be combined underneath the first season of the SPACE Press Event?

Seen as such:

SPACE Press Event (2025-)

• S1E1 - SPACE Press Event v1
• S1E2 - SPACE Press Event v1.2
