This should work ok. Try
\placeformula[ref]
\startformula\eqalignno{
 a &= b &\formulanumber[refa]{a}\cr
 b &=c & \subformulanumber[refb]{b}\cr
}\stopformula
\in[ref], \in[refa], \in[refb]

or

\placeformula
\startformula\eqalignno{
 a &= b &\formulanumber[ref1]\cr
 b &=c & \formulanumber[ref2]\cr
}\stopformula

\in[ref1], \in[ref2]
