excel cell format general(important)

Hi

we migrated from 3x to 4.1

3x:

if I export webi document to excel,all cells format becomes general.this is good for us because when we add column exported excel,new cell becomes general because in front of new cell is always general so we dont have to change format type to general.

4x

if I export webi document to excel,some cells become text,some cells become general.It is easy to change text format to general but it is a lot of work for users.we always want 4x excel cell format to be general.

is it possible.

thanks for your help
