New label with parameter

[umrenato]

Would it be possible to modify the command \SetEnumitemKey so it could define a new label with one parameter (maybe more)?
In the readme pdf, consider the example that defines a twocol label. I'd like to modify it, being able to define a ncol label, so that we could add ncol = 3 to the list options and have the desired number of columns.
Something like this:

\SetEnumitemKey{ncols}[1]{ %specifies that it has 1 parameter
itemsep=1\itemsep,
parsep=1\parsep,
before=\raggedcolumns\begin{multicols}{#1},
after=\end{multicols}}

So we would use that new key like this

\begin{enumerate}[ncols = 3]

or maybe using some other notation, like

\begin{enumerate}[ncols{3}]

This last one could possibly be extended to allow something like this with more parameters...

\begin{enumerate}[mykey{3}{4}]

While admittedly it could be useful in some contexts, I'm sorry to say I have no plans to add it. Actually, long ago I even began to write it, but it turned out to be more complicated as it seems at first sight.

Thanks for the answer! Anyway your package is great. It has been a default for me since I have found it.
