BW workbook and roles

Hi guru

I have a problem :

I have one role in PFCG for access from BEX to the query of an infocube.

Under this role there are some workbook saved by the user.

My question is : if I cancel the role all the workbook are lost ? Is there a Way to save the workbook and assign the workbook to another role ?

This is because I need to recreate the roles in PFCG for query access reorganization, but i'm confused on assigning the workbook to the new roles

Thank' in advance
