You cannot have two * selectors in a scatter file. You can, however, use two modified selectors, for example *A and *B, and you can use a .ANY selector together with a * module selector. The * module selector has higher precedence than .ANY. If the portion of the file containing the * selector is removed, the .ANY selector then becomes active.
