Reuti,

having two line sounds good for me. However I don't like the idea of 
changing the consumable name by adding the '_ar'. I would suggest adding 
a new layer character 'a' , for example:

hc:virtual_free=300.000M
ac:virtual_free=500.000M

Can you please file a IZ mentioning the request.

Thanks
Roland
