Is it possible to add a "Search/Lookup/Relation" in an Upsert with Salesforce?

Hi all,


In SalesForce they use "SOL Queries" and they are able to put a search into a "SOL Query" and that everything is handled by salesforce. F.e.: select Id, Name,, Customer_Service__r.AX_User_ID__c from Account where Id = '0016E00000YzWMOQA3'.


I want to be able to give such "Search/lookup/relation" into the "Upsert"-block in "Scribe Insight".


Is that possible, because we want to reduce the "API Calls" to "Salesforce". Instead of an extra call, Saleforce does it when receiving 1 call.


Kind Regards,
