4* feeder for 5* Captain America (First Avenger) overdue

Bullroarer

5* Captain America (First Avenger) hasn't had a 4* feeder since the widescale changes to feeders in later 2022 and early 2023.

Initially I thought that this might be because a new 4* feeder relationship was in the pipeline but almost two years later this character still doesn't have one.

Given that it's the only 5* character without a 4* feeder I can only assume that it was an oversight.

Could this be addressed, please?

It's definitely overdue.

PS, in case anybody is wondering, thematically, of the 4*s that don't yet feed a 5*, 4* Agent Coulson (Agents of SHIELD) appears to be the best feeder choice.
