While forming an ($A$+2) nucleus from a nucleus $A$ via a two-neutron transfer reaction, the constructive interference of the many possible reaction channels favors significant pairing enhancement through the continuum of the intermediate ($A$+1) nucleus [Phys. Lett. B \textbf{834} 137413 (2022)]. I analyse this situation in more generality, from the point of view of a varying pairing field and different continua leading to the formation of ($A$+2) nucleus. I consider $^6$He and $^{22}$C, described as housing two-neutrons in orbitals of $^5$He and $^{21}$C, respectively. The different possible situations manifest that the continuum correlations are extremely crucial to the extension of the pairing enhancement observed in the system.
