event series feel very wrong.

if i look how the direction works in festival events it feels logic (like a tree structure)

• Rock Herk 2024 (event)
  • Rock Herk 2024, Day 1 (event)
    • Rock Herk 2024, Day 1: Mainstage
    • Rock Herk 2024, Day 1: Club
  • Rock Herk 2024, Day 2 (event)

• • • Rock Herk 2024, Day 2: Mainstage
    • Rock Herk 2024, Day 2: Club

but the festival series isn't the thrunk of the tree. from the Rock Herk 2024 -> Rock Herk should be a backwards direction. but in the data it is a forward direction.

so the data in tree view is like:

• Rock Herk 2024 (event)
  • Rock Herk 2024, Day 1 (event)
    • Rock Herk 2024, Day 1: Mainstage
    • Rock Herk 2024, Day 1: Club
  • Rock Herk 2024, Day 2 (event)

• • • Rock Herk 2024, Day 2: Mainstage
    • Rock Herk 2024, Day 2: Club
  • Rock Herk (series)

while it should be:

• Rock Herk (series)

• • Rock Herk 2024 (event)
    • Rock Herk 2024, Day 1 (event)
      • Rock Herk 2024, Day 1: Mainstage
      • Rock Herk 2024, Day 1: Club
    • Rock Herk 2024, Day 2 (event)

• • • • Rock Herk 2024, Day 2: Mainstage
      • Rock Herk 2024, Day 2: Club
  • Rock Herk 1983 (event)
  • ...
