Hi Mikki
You would just need to get your method queries into the same format (if they aren't already) and then merge the 2 datasets/data tables together.
Syntax for the method command is:
Dim objDataSet As DataSet = BRApi.Database.ExecuteMethodCommand(dbConn, methodTypeId, methodQuery, resultDataTableName, customSubVars)
There is an example of using method queries including looping through and working with the data within here:

There is a fair amount of info on google about joining data tables so I'll leave that to you!
