  Ultra-High Energy (UHE) neutrinos over $10^{16}$ eV have yet to be observed
but the Askaryan Radio Array (ARA) is one in-ice neutrino observatory
attempting to make this discovery. In anticipation of a thorough
full-observatory and full-livetime neutrino search, we estimate how many
neutrino events can be detected accounting for secondary interactions, which
are typically ignored in UHE neutrino simulations. Using the NuLeptonSim and
PyREx simulation frameworks, we calculate the abundance and usefulness of
cascades viewed by multiple ARA stations and observations made of taus, muons,
and neutrinos generated during and after initial neutrino cascades. Analyses
that include these scenarios benefit from a considerable increase in effective
area at key ARA neutrino energies, one example being a 30% increase in ARA's
effective area when simulating taus and muons produced in $10^{19}$ eV neutrino
interactions. These analysis techniques could be utilized by other in-ice radio
neutrino observatories, as has been explored by NuRadioMC developers. Our
contribution showcases full simulation results of neutrinos with energies
$3\times10^{17}$ - $10^{21}$ eV and visualizations of interesting triggered
event topologies.
