[Scip] Question about the resultant of a constraint

Hi SCIP folks,
I am pretty new to SCIP. A quick and specific question. Can I use the
resultant of a OR constraint as a variable in another linear constraint?
Adding some details, I am going to solve such a question:
r1 = x1 OR x2 OR … OR x_m1
r2 = x_(m1+1) … OR x_m2
….
rk = x_(m_(k-1) + 1) … Or x_mk
lhs <= c1*r1 + c2*r2 +… + ck*rk <= rhs
So r_i are resultants of those cons_or instances. While in the linear
constraint, r_i are used as variables. Is it valid to `SCIPgetResultantOr’
to obtain r_i and directly add it to the linear constraint?
BTW, to me, cons_or is something more like an operation rather than a
constraint. Correct me if I am wrong, please.
Best regards,

Gang
