Google Analytics Importer - Re-Import

Hello,
I have the following problem - I added data to a SiteId via Google Analytics importer and after the import was completed, I also deleted it from the GAI. Now I’ve found that some not correct data and I have to do a re-import. Now the page is no longer listed for re-import in the GAI. How or what do I have to do?

Greetings Mitch

Is an Re-Re-Import possible?
