Having more than one signing authority for a certificate

Hello all,

I am new to Blockcerts and am wondering, if we can have more then one signing authority for the certificate (More than one Issuer if I am not wrong). (i.e.) if a certificate needs to be signed by the University & Education Bureau of state after creating for it to be valid, and also needs to match both signatures while verifying etc., If we can, then how can we do that.
