Configured Item name

Hi all,

For the first time, I created a model. Everything went fine (rules, structure and publications). I could even get the configuration done.at

The rule for the configured item name generated is : CG followed by the id of the model, followed by R and a sequence.

My problem is that the rule considers the id to be 6 digits long, although my new model is 7 digits long. So I get something like CG#######R00001

I would like to change the structure to consider, from now on, 7 digits. Could you please indicate where this info is set up?

Thanks in advance,
