Labelling for unroll

Hi,

I'm trying to label and unroll up to 400 surfaces from rhino. Each has to be given a numeric or coded value. I have two issues.

01. My issue is that the model is being updated constantly with new panels or panels are changing and every time this occurs, the labels change. Is there a way to maintain the same label for each piece of geometry that is existing? Then each new piece of geometry will be added to the end of the list.

02. Is there a way to make all the text read as horizontal? It must be 3d text and not a 3d Rhino tag as our consultants don't use Rhino.

I'm relatively new to Grasshopper so any and all help is appreciated.

Jordan.
