  Fascination with glassy states has persisted since Fisher introduced the
vortex-glass as a new thermodynamic phase that is a true superconductor that
lacks conventional long-range order. Though Fisher's original model considered
point disorder, it was later predicted that columnar defects (CDs) could also
induce glassiness -- specifically, a Bose-glass phase. In
YBa$_2$Cu$_3$O$_{7-x}$ (YBCO), glassy states can cause distinct behavior in the
temperature ($T$) dependent rate of thermally activated vortex motion ($S$).
The vortex-glass state produces a plateau in $S(T)$ whereas a Bose-glass can
transition into a state hosting vortex excitations called double-kinks that can
expand, creating a large peak in $S(T)$. Although glass phases have been
well-studied in YBCO, few studies exist of other materials containing CDs that
could contribute to distinguishing universal behavior. Here, we report on the
effectiveness of CDs tilted ~30$\deg$ from the c-axis in reducing $S$ in a
NbSe$_2$ crystal. The magnetization is 5 times higher and $S$ is minimized when
the field is parallel to the defects versus aligned with the c-axis. We see
signatures of glassiness in both field orientations, but do not observe a peak
in $S(T)$ nor a plateau at values observed in YBCO. We discuss the possibility
that competing disorder induces a field-orientation-driven transition from a
Bose-glass to an anisotropic glass involving both point and columnar disorder.
