Import Multiple table SAP Analytic Cloud

Hello,

I established a Connection between SAP Analytics Cloud and AWS Redshift in order to import tables

I'd like to import all my tables at once and link them to create a Data model (Like in Power BI)

However I can only do 1 table by one, resulting in the creation of a data model for each tables

Is this the way to proceed ? Not sure since I'm really new using SAP analytics Cloud

Thanks !
