Quickstart transforms filter on the  _FIVETRAN_DELETED column.  All Transforms have identical code.  Here's a code sample:

FROM   "RAW"."SALESFORCE"."USER"  AS mt

WHERE NOT mt."_FIVETRAN_DELETED" 

Our problem is that we're reading from the Quickstart views and building Slowly Changing Dimensions (Type 2)  models.  When we see a record added or modified, we make the appropriate change to our models.  But when the record is soft-deleted, it just disappears from Quickstart views, so we don't know it was deleted.  Right now we have records in our models that look like they're active, but have been deleted, the _FIVETRAN_DELETED is True.

We'd like to have the Transformation filter on _FIVETRAN_DELETED to be optional.  When we choose to not filter, the records with _FIVETRAN_DELETED set to True would be visible in Quickstart tables/views.    

For our purposes, one Y/N option for all Transforms would be perfect.  But a separate option for each table would also be fine.
