Arnold Volume wildcard in ar_grids parameter

Hello,
when setting up VDB volumes with Arnold Volume OBJ node, there is Grids parameter. When clicking on drop-down menu, it shows available grids and it also shows * (all grids) option, which should import all available grids.

Using wildcard in Grids parameter however does not work, Arnold outputs this warning:

00:00:00   102MB WARNING |   [volume] could not find non-empty "grids" user data, cannot create volume

Do you plan fixing this bug? I have a situation where I have changing names of grids each frame and using wildcard for importing all of them would help me.

Workaround for now I guess will be using some Python expression, which will return all grids.

Thanks,
Juraj

Also in your docs you have an example image which has wildcard in it.
