It would be helpful to be able to merge data that has the same data type. For example I might be tracking behaviors separately (e.g. tantrum, elopement, etc.), but would like to be able to see how many total (all behaviors together) occur. This could also be used to merge duration data if you are tracking it separately for different environments (e.g. home vs daycare) or requesting data (e.g. single words & short phrases) to get a total requesting view.
