Can Khovanov homology have arbitrarily large torsion?

That is, given $N\gg 0,$ does there exist $k>N$, a knot (diagram) $D$ and $i,j \in \mathbb{Z}$ such that $\operatorname{Kh}^{i,j}(D) = \mathbb{Z}/k\mathbb{Z}$?

This paper from earlier this year (Jan 18, to be precise) proves the existence of $\mathbb{Z}/n\mathbb{Z}$-torsion for $n\le 8$ and $\mathbb{Z}/2^s\mathbb{Z}$-torsion for $s\le23$. It also states at the beginning of Section 3.4:
Until now, no knot or link with torsion larger than $\mathbb{Z}/8\mathbb{Z}$ was known.
Computations suggest that $T(p^k,p^k+1)$ should have $\mathbb{Z}/p^k\mathbb{Z}$-torsion for each $p$ prime and $k\ge 1$.
