Nowadays High Energy Physics experiments can accumulate unprecedentedstatistics of heavy flavour decays that allows to apply new methods, based onthe study of very rare phenomena, which used to be just desperate. In thispaper we propose a new method to measure composition of $K^0$-$\overline{K}^0$,produced in a decay of heavy hadrons. This composition contains importantinformation, in particular about weak and strong phases between amplitudes ofthe produced $K^0$ and $\overline{K}^0$. We consider possibility to measurethese parameters with time-dependent $K^0 \to \pi^+ \pi^-$ analysis. Due to$CP$-violation in kaon mixing time-dependent decay rates of $K^0$ and$\overline{K}^0$ differ, and the initial amplitudes revealed in the$CP$-violating decay pattern. In particular we consider cases of charmedhadrons decays: $D^+ \to K^0 \pi^+$, $D_s^+ \to K^0 K^+$, $\Lambda_c \to p K^0$and with some assumptions $D^0 \to K^0 \pi^0$. This can be used to test the sumrule for charmed mesons and to obtain input for the full constraint of the twobody amplitudes of $D$-mesons.
