SVG id (tag) not found in Objects (Object Manager)

Using rStones plugin, creates is a bunch of identical objects, differing only in coordinates.

I File | Save As (or File  | Export) to a .svg file, and the objects' tags appear as:

  <path id="RS-04A203_101" ............

However, the object name in the Objects list only shows "RS-04A203"

Two questions come to mind...

1) What generates the "_101" tag ending, and

2) Why is the "_101" tag ending not shown in the Objects list, as a searchable, or locatable item?

Since there may be thousands of these objects in any particular document, it is quite unhandy to have to hunt for some particular id, by name, or click items either on the Objects list, or on the workspace, in an attempt to find a particular item.
