Our standard replica set deployments require a number of items to be set in the edit/modify area of each replica set...such as:
sslMode
directoryPerDB
directoryForIndexes
javascriptEnabled
redactClientLogData

Since we create hundreds of replica sets the amount of time spent repeatedly setting these attributes, which are considered "default" in our shop, adds up. Having the ability to set a template of defaults per project would save a great deal of time.
