Is your feature request related to a problem? Please describe.
In MCNP fill cards are added to cells filled with a given universe. When a model is output from GEOUNED it is currently necessary to manually find the cells which need to be filled with a given universe. This can be time consuming and adds an extra step into the model creation workflow.
Describe the solution you'd like
Being able to tag components in the CAD tree structure as being filled with a certain universe number and transform card would allow for an easy way to mitigate this problem. This could be done in a similar way to materials, e.g. with fn and tm where n universe number and m is the transform (tr) card number. The code could then assign a 'fill=n (m)' to the relevant cells during writing of the mcnp input file.
Describe alternatives you've considered
No other implementations considered.
