Setting the same boundary condition at multiple patches at once

I am currently working with snappyHexMesh to create a mesh which has a number of regions cut out. I have named these "obstacle1","obstacle2" etc

All these obstacles should have the same boundary conditions. When setting them I am already using the following structure:

Code:

obstacle1_region0

    {   

        type fixedValue;

        value uniform 3;

    }   



    obstacle2_region0

    { 

      $obstacle1_region0;

    }



     obstacle3_region0

    { 

      $obstacle1_region0;

    } 



etc

This saves me some time, but it is still a little annoying to have to add new obstacles in U, p, alpha1 every time I change the number of obstacles.

My question is:
is it possible to set the boundary condition for patches with repetitive names in 1 go? I could imagine that would look something like this:

Code:

obstacle$i_region0 

{

     type fixedValue;

     value uniform 3;

}

You can use regular expressions in the patch names, like:

Code:

"obstacle.*"

{

     type fixedValue;

     value uniform 3;

}

for all patches starting with the string "obstacle". More refined expressions can of course also be made.
