Installing a kwinrule alongside a package

Hi,

is it possible to install (and update) a specific kwinrule by the command line?
Is there maybe something like kwinrules.d/ ?

Context: I programmed myself a small clock that I use with a specific kwinrule (layer: overlay , no window decoration, etc.) and I plan to distribute it.
Today my plan is to just ship an importable kwinrule and will document that it is necessary to import it. For a better user experience, it would be great if I could just drop the kwinrule into a specific directory and maybe update this rule with an update of my software.

Thanks for having a look!
