Can we update embedded data subsequently once the responses have been collected

Hello all, Current situation We receive customer database and survey invites get sent out through Qualtrics. Along with the contact information we receive a lot of other useful information like 'region', 'customer type' etc. as embedded data fields. Challenge faced Some of the data fields are not updated in the data that flows through for surveys. Eg. - There may be blanks or may be incorrect data at times. However, business is able to share such data subsequently (after responses have been captured). So the way we currently analyse this is by downloading the completed responses from Qualtrics in excel, then do a Vlookup to match it with the updated information recieved for each respondent and subsequently analyse it manually. Key questions Q1. Are somehow able to update the embedded data in Qualtrics with the accurate data received separately? Eg. There is a sample of 1000 respondents (each having a unique ID) in Qualtrics but while viewing the data in the dashboards we realise that the embedded data for 'regions' was missing for 400 cases when the data flowed through initially. However, subsequently we are able to get the correct data separately in excel. In such a case can we update the existing data in the dashboards and use it in statsIQ Q2. A certain field eg. 'Sales Value' for a customer was never a part of the embedded data received for sending out surveys but this data is available separately at a later stage (after responses have been collected). Let's say we have collected 1000 responses and would now like to add that data subsequently in the dashboards and would like to analyse it in statsIQ, is it possible to do that?
