I do not see "Add a Field" when using Looker as Source in Looker Studio

Hi,

I am unable to “add a field” when using Looker as a source in Looker Studio. Assuming this is a known limitation, are there any workarounds?

Confirmed that adding calculated fields is not available for Looker sources in Looker Studio.

I suppose as a workaround you could download a result set from Looker and then upload it into Looker Studio?
