Yes, indeed, repeatability and other improvements to the LiveOps Events feature are in our backlog. However, I can't currently provide a schedule on when they would arrive.
You can still achieve repeatable events with our config-driven In-Game Events feature (also called "Activables" as a broader term encompassing also Offer Groups and Offers), see here for comparison of the two and for more info:
https://docs.metaplay.io/feature-cookbooks/in-game-events/introduction-to-game-events.html
As of Metaplay Release 34, the In-Game Events also show up on the timeline view of the LiveOps Dashboard (in a read-only sense, since their configuration is from the game configs).
