How to list all possible values UBA can use for certain fields?

[att35]

Hi,

Is there a way to find out all values that UBA can understand for a certain field? e.g. Under Cloud Storge,
http://docs.splunk.com/Documentation/UBA/5.2.0/GetDataIn/CIMtoUBAfields#Cloud_Storage_category

For change_type, example column lists following.

Download, Preview, Delete, Create, Edit

Could there be others, e.g. Upload? There are other fields where the example set seems very limited.

I believe we can add additional values under 

/etc/caspida/local/conf/normalize.rules

but how do we ensure that UBA does understand those?

Thanks,
