Drobo 5D3 and Time Machine

With a previous DROBO I was able to create a separate Time Machine compartment on the Drobo and a separate Compartmen/Drive for my other Mac data. When I upgraded to a 5D3 I wasn’t able to do the same. Now I have just some mac drives on my DROBO but no time machine compartment. Does anyone know if it is now possible again to set up my DROBO with bith Time machine and normal drives/Compartments?

Many thanks, Richard
