sending multiple Class attributes in Rest POST

Hi there Is there a way to be able to POST multiple Class attributes using Rest? I am currently testing returning multiple class attributes and can see they are being sent in the accounting-request trace: (10) Framed-IP-Address = 10.192.230.1 (10) Class = 0x31323334353637383957424149443d64756d6d792e6d656d6265723a5553 (10) Class = 0x37334a773b51793453716c44264e5548405929 Is there a way I can pass both received class attributes in a rest POST? It looks like the Rest %{Class} simply picks the first one. Cheers, Mark
