My issue is that if I create a calculated member with PT Extensions and then use the build in excel 2010 feature to create a set which uses the newly created calculated member, this first of all works pretty fine
until I change the definition of one of the calculated members.
 
The inconvenience that then exists is that you have to re-add the set whenever you change any of the calculated members.
 
Is there any chance to change that?
 
Best regards
