Can I Check a Scan Result with an Existing List?

Hello… Is it possible to run a scan and then check the result with a list created by a previous scan? If I could, I could eliminate hits from a scan that had previously come up or I could eliminate stocks that I had decided I did not want to look at.

This would be good to achieve but I am not sure it can be done. Does anyone know if it can be done?

Many thanks in anticipation
