Help with one modification to existing content center o-rings

[claudio.ibarra]

All of the tutorials I can find are for brand new Content Center entries based on existing ones. Is it possible to edit an existing one? I want to add the option for "captured" vs "regular" to the existing o-rings in the content center. All existing ones become "regular" and the "captured" option would change one parameter (groove inside diameter) to reduce it by 4%. 

Is this possible? Is there a tutorial I should look at? 

Please forgive my poor MS Paint skills. I am also currently using Inventor Pro 2018.

You can't edit the ones provided since they are read only.

You have to create your own and copy over the family needed this additional key column.

Is it possible to tell if I'm looking at a provided one or a copy? I want to say it's a copy (made before I joined the team) because there's already a column for the company-specific part number in the Family Table. 

Is it as easy as:

1) Editing the Family Table in Excel

2) Adding a column for "captured"/"standard"

3) Copying all of the existing ~350 rows (putting "standard" in the new column)

4) Pasting additional rows (putting "captured" in the new column)

5) Changing the nominal diameter for the newly copied rows to be 4% smaller than the "standard" sets.

6) Doing something to add the new column as a selector choice when adding from the content center
