sql2008 R2 - SSRS to update all reports and its parent folder with role assignment

Guys,
Does anyone knows how we could do mass updates in SSRS  systems table to assign role permission to folder,  my problems is now I have too many folder and reports to be updated so I'm thinking if we could do this via T-sql that is easier for me.

Can't you do that on Windows? Just right-click on the parent folder, Properties, Security tab, Advanced and check the "Include inheritable permissions from this object's parent".
