Mass Change Lead Source and Lead Source Detail

A list of around 500 new leads was uploaded into our Marketo last year, without lead source or lead source details.

I am now trying to change all the values in one mass update. I have tried to set up a batch smart campaign but it blocks out all those with a current lead source (which have been picked up since being entered last year through various other forms of activity/engagement). 

I tried pulling a smart list of all the members of the program then 'change data value' - lead source: Event but this just does nothing, even though it says complete. 

Is the only way to do it via a new upload in Salesforce?
