Member Formula. 255 characters limitation and Options file

Hi SAP BPC experts,

We are facing an issue regardind a member formula that cannot be longer than 255 characters.

Once we are in this point we have two questions:

1. Is it possible to change the configuration (some application or application set parameter) in order to allow longer formulas?
2. Is it possible to work with longer formulas is we use the Options in the right side of the Member Formula screen.
   1. The file supports MDX syntax or is another different programming language?
   2. Where do we need to store the file and what name should we use?
   3. Is this file somehow related to the script logic files?

Best regards and thanks in advance
