Get data with Direct Query and Import Data

Hi All,

Recently I am designing a new report in Power BI Desktop. As its data is too big, I load data from Oracle database using Direct Query. After that I realized that I need to Get some mapping data from Excel. But Excel only support Import data mode. If I switch whole report to Import data mode, it will spend a lot of time in loading and refreshing data from database. Is there any way that support both get data method? Is there any solution for this condition? Thanks in advance.

Ha Da.
