Is Excel force closing or going unresponsive? It's pretty common for it to go unresponsive when requesting a lot of data, but should eventually come back if left to work long enough.
Unfortunately, with BAAAM there is no way to adjust the request made to filter the results anymore. I would suggest making a manual request with our REST API
For example you can filter by folder ID:
https://api.demdex.com/v1/traits/?restrictType=RULE_BASED_TRAIT&folderId=111111
or data source ID:
https://api.demdex.com/v1/traits/?restrictType=RULE_BASED_TRAIT&dataSourceId=12345
