  It was recently shown that odd-frequency superconducting pair amplitudes can
be induced in conventional superconductors subjected to a spatially-nonuniform
time-dependent drive. It has also been shown that, in the presence of interband
scattering, multiband superconductors will possess bulk odd-frequency
superconducting pair amplitudes. In this work we build on these previous
results to demonstrate that by subjecting a multiband superconductor with
interband scattering to a time-dependent drive even-frequency pair amplitudes
can be converted to odd-frequency pair amplitudes and vice versa. We will
discuss the physical conditions under which these pair symmetry conversions can
be achieved and possible experimental signatures of their presence.
