Hello,

is it possible to change index settings between phases?

I have a issue with moving index to warm phase and then shrink with index settings `index.routing.allocation.total_shards_per_node = 1`. Because of shrink action, I need to have all shards on one node, which is forbidden by this particular settings. Is there any way to keep that settings on indices and also sucessfully shrink an index?
