[Inkscape-user] auto-increment object id's?

hey,

i use inkscape a lot - it is my primary svg editor - and i'm very impressed with it. but there's one thing that frustrates me, and that is the way it handles auto-id assignment.

ideally i'd like to be able to select a group of objects, set the ID property of one, with a -1 at the end, and have the rest all be enumerated based on the first one..

is there any way to tell inkscape to use specific id's for objects, and auto-increment properly? i've dl'ed the code and had a look at the sd-object "sp_object_get_unique_id" function, but it doesn't look to me as if theres' an 'easy' way to get it to handle auto-increments properly without majorly restructuring things .. anyone got clues?
