Connect to Bex query after logging into Web service

Hello experts,

After logging into the web service, I see connections for all HANA and BW infoProviders.

If I click HANA OLAP connection, I see the "next" button. If I click connections to BW InfoProviders, the "Next" button is grayed out, I only have "OK" to click which takes me to the infoProvider.

I know if I choose "Local System", I can log into BW and find BEx queries.

Is this by design? Can't we get list of Bex queries under the connection we highlight somehow?

Thanks.
