Is there any way to deal with Cluster Size in Foliage Tool?

Hi, guys!
I want to be able to cull my instanced foliage meshes one by one, or by small clusters, but it seems to be no such easy way to do this, as it was in 4.7 version with changing “Max Cluster Size” value in the foliage tool. Clusters are very large now.
And by the way, it seems, that LOD’s screen size for instanced meshes calculates for clusters, but not per instance, its a problem too.
So is there any way to change clusters’ sizes, or do something, what brings the same result?
