zeroLength element: recording multiple materials

[amia]

Is there a way to record multiple materials for a zeroLength element using a single recorder?

I'm able to record a single material (i.e. material assigned to a degree of freedom). For example, I can record the moment-rotation material response in the 6th dof using:
recorder Element -xml $Path/$filename -ele 1 material 6 stressStrain

However, I'm not able to record more than 1 material at a time, say the material response in the 4th and 6th dof. I have tried the following:
recorder Element -xml $Path/$filename -ele 1 material 4 6 stressStrain
recorder Element -xml $Path/$filename -ele 1 material 4 stressStrain 6 stressStrain

I'd like to record the different dofs in one recorder because I am exceeding the number of files that can be recorded in one go during an analysis..

Many thanks in advance

You can use the force recorder to record all forces of the zerolength element. Below is an example:

recorder Element -file name.out -time -ele 11 force;

Thank you for your suggestion, I think that's the best option. I was hoping to use the stressStrain command because it automatically recorded both the force and the deformation but it appears to be limited to a single dof.
