Any progress or workarounds for adding atlas parameter to CurveAtlasRowParameter

Hi,

We want to change Curve Atlases within Material Instances’ Curve Atlas Row Parameters, but only the curve can be changed.
There is a bug for this that was opened in 2023, UE-188447, which has a target fix of 5.6. Is this still a likely target fix?
If not, do you have any advice on how we can solve it on our own?
