Yep, it sure can.

track-account-range = ["jesta","biophil"]

I believe this sets the node to only track these two accounts history. I'm not sure of the exact details, but I have a node running with these settings:

shared-file-dir = /dev/shm/
shared-file-size = 20G
public-api = database_api login_api account_by_key_api network_broadcast_api
enable-plugin = witness account_history account_by_key
track-account-range = ["jesta"]

and the node is only consuming ~16gb of ram/space (instead of like 50+).

I'm not sure what account-stats-tracked-account does. Might have to go look that up.

Edit - Went and searched the code base for account-stats-tracked-account, couldn't find anything about it. Maybe it's a legacy thing that got removed?
