Inserting a new field

Hi, i`ve been trying to insert a new field on my extended atributes but i don`t want to insert it on the bottom of the fields. I have many fields created and i will waste a lot of time, placing it on the right position.

I`ve been trying to:1 - Export as an xml file2 - Edit the xml file that i exported (creating an new root line but with a random Id) to place the field on the right place on the <ExtendedAttributeOrderList>3 - Saving it as xml and import to my process again.I find an error and the bizagi won`t let me import it. Any ideas? How do i generate an valid Id ?

I`m wasting a long time for simple things like repositioning the fields.
