Irish Citizen Living in UK, require multi-entry Visa

I am Irish citizen living & working in the UK, but I am involved in projects in China and so have regular business travel there. If I get my application processed in London I only ever get a double-entry visa which can be quite restrictive. If I applied in Dublin would I be granted a multi-entry visa? Is there any way I can do this remotely? i.e. a processing company who can take my Passport to the embassy if I post it to them.
