Question on Mass Delete: If you upload cvs file and you realize the lead data is incorrect. Can you put them in queue going forward to where anything is imported waits in queue for a certain time period just in case any issues like this arise. It gives till the end of day to validate the upload.

I did delete the wrong lead data. However, I found that as I filtered the data some field still appeared even though filters were drilled down.

Thoughts or solutions would be appreciated.
