  In this paper we conclude the program of 2012.15792 and 2105.00257 about
perturbative approaches for $\mathcal{N}=2$ superconformal quiver theories in
4D. We consider several classes of observables that involve multitrace local
operators and Wilson loops scattered in all the possible ways among the quiver.
We evaluate them exploiting the multi-matrix model arising from supersymmetric
localisation and we generalise the solution to both $SU(N)$ and $U(N)$ cases.
Moreover, we provide QUICK (QUIver Correlator Kit) a Wolfram Mathematica
package designed to automatise the perturbative solution of the $A_{q-1}$
multi-matrix model for all the observables mentioned above. Given the
interpolating nature of the superconformal quiver theories $A_{q-1}$, the
package is an efficient tool to compute correlators also in SCQCD,
$\mathcal{N}=4$ SYM and its $\mathbb{Z}_q$ orbifolds. This manuscript includes
a user guide and some pedagogical examples.
