Valentina- Yes, you can combine un-related data sets into a single Omniscope file by appending/concatenating the two files. In DataManager, the source of each record is added as a column, and the source value can be used to focus views and queries on only one subset of the appended data set at a time. In DataManager, you can also define an entire folder of workbooks as a source, and all sheets within all the workbooks will be automatically appended on every data refesh.
