Boundary blend surfaces in Sheetmetal module

Hi Friends,

my query is in sheetmetal module,

while creating the complex sheetmetal parts, we use sufrace options  (boundary blend etc) and convert that as a first wall. And then the flat  pattern option is clicked all other bends except the boundary blend  region unbends. is there any option to flatten those bends in pro e ? (since the sheet metal part is accepted as a first wall, why its not unbend ?)

In our firm we use a third party software to flatten such complex shaped sheetmetal parts.
