How can I use more than one Alert Log?
First Go to Settings >> Application >> General >> Save the Alert Log between sessions for X Days(Default 0) set to 0. Then Go to Alert Editor >> Choose Portfolio(CEFs) >> Note/Speech
Add custom description to the alert, for example "winCEFs". When you Apply then you have to change other portfolios in Notes/Speech.
Open New Alert Log Window >> Main >> New Window
Open Alert Log >> Main >> Desc(Write same filter which you want to see)
