Good afternoon Reinis,
I have devised a way for you to automate this process.
First Option:
Lets assume you have a childcode Set like this and you want to code all the citations that are coded with Child 1 or 2 or 3 as "Childcode Set."
1. Use the Search Function (See pictures below) to create a list of all your child codes
A. Click here
B. Then here
C. Then here
D. Then select your first child code
E. Then repeat the process to search for all citations with your child codes
F: You should then have a search that looks like this:
G: Select all the child Codes
H: Select "OR"
I: Click "Combine"
J: List all these citations by clicking "Select"
K: Click this button to select all the citations
L: Right click on the parent code in the codeset bar and click "Assign Selected Items to this Code"
M: Celebrate because you're done!
Cheers,
V
