I am interested in increasing the number of conditions I apply.

Currently, excel offers 3, I need 4.

If severity of case is Business Critial and Age in Days is greater than 3,
then color case id blue.

If severity of case is High Urgency and Age in Days is greater than 6, then
color case id red

If severity of case is Low Urgency and Age in Days is greater than 14, then
color case id yellow

If severity of case is Routine and Age in Days is greater than 30 then color
case id light tan...
