Sarcochilus hartmanii, can they be split up like cattleyas?

[headbanger333]

Hello all, my friend has inherited a huge very old Sarco that has innumerable lovely spikes every year. Is it possible to split it up? I am not sure if they have only a central rooting system or whether the new growth clumps grow from a rhizome with their own root system, like cattleyas do. Any advice greatly appreciated, as I would like a piece of it.
