Create Boundary Conditions in a local coordinate system (Solver: Abaqus)

Hello there,

I need to create local boundary conditions in HyperMesh, which refer to a cylindrical coordinate system I just created. I am using Abaqus as a solver. image

In the picture you can see how I do assign the nodes to the local cylindrical coordinate system. 
My input file says that those nodes are assigned to that coordinate system as you can see below.

I want to constrain the DOF 2 4 and 6 but not refering to a global coordinate system.

My boundary conditions for that nodes look like this. I know that 2,4,6 does refer to the global coordinate system here, because it gives me the same results even if I do not create that local system before. Also if I open my Input File in Abaqus it says the boundary conditions "Boundaries" refer to the global coordinate system.

 

Is there any workaround for that? I can not find the code for the input file to change the boundary conditions to local. I know that it works for other solvers. 

Thanks for your help
