No command course in SIA Cargo for anyone yet, but I believe that there are some plans for command courses for the future. However, this being Singapore, there is (surprise, surprise) a catch. If you are an F/O on contract terms you have to accept a local contract for (I believe) a period of 2 years before being 'considered' for command. If you have 2 children in school in Singapore then thats a combined loss of Housing and Education Allowance of $6150 per month - for at least 24 months - and all for the 'chance' of a command!
Hardly surpising then that we have a lot of experienced and capable F/Os on short finals to the sand pit and Japan.
