QAPI Action for creating item groups from full path names

At present, in Datalink one cannot create a category with items organized hierarchically, e.g. a directory tree or an XML document with nested elements.
In order to do that, one way would be to use datalink to import into a category a column of strings representing full path names, i.e. item names with possible parent group name(s) prepended, all separated by a given separator. As an example, a tree with separator “//” would be represented in this way:

A//alfa//x
A//alfa//y
B
C//alfa
C//beta

I have programmed a very simple action that I would like to share.
Such action transforms a flat category containing “full path” item names into a hierarchy of item groups and items.
It could be run after importing the path names with datalink.
To try it, download the enclosed plugin zip file and extract it in the quantrix program directory. In Modeler, from the Tools menu, select the item “Create groups from full path item names”. The current implementation has settings hard coded into the action: the category to “hierarchize” is the first row category in the currently selected matrix, and the separator is “//” (double slash). Error trapping is rudimentary.
I enclose a sample model .
