Nomenclature for composite knots with hierarchies

I'm not a mathematician but highly interested in knots form a biological perspective, so I hope everyone is fine with me using a less mathematical formalism to express myself in this post!

Recently, I've been curious about how what to call knots that have several different orders of "knottiness". For example, many celtic knots have C3 or C4 symmetry with knots attached at the outer rims along with a further entangled element at the center of the system. In the image below, two celtic knots are attached that illustrate my point. The image shows a knot to the left that is clearly simple to name and one to the right that is the source of my question. The left knot is obviously a [3_1]#[3_1]#[3_1]#[3_1] composite knot. However, the central core of the right knot (or link, more specifically) is mechanically interlocked and cannot be transformed into simpler knots. My question is then - how do you name a knot/link where there is a central interlocked element such as this one, and knotted elements along the edges. Or - in essence - what is the nomenclature for a knot/link with hierarchical orders of entanglements.

The link on the right can be described as having L4a1 as the core, and each component of the link is connect summed with two copies of $$3_1$$. One ought to be a bit careful with orientations, however, since both L4a1 and $$3_1$$ are chiral.
