Pro|E: Change BOM balloon type

If the default BOM balloon bubbles don't meet your standards, you can replace them with custom "symbols".

1. From the Dropdown menu: Table/BOM ballooons....
2. To change
   
1. All balloons: Pick "Change Type", then click the repeat region of the table.
2. Selected Balloons: Pick "Alt Symbol", then select those balloons you want to change. This appears to work only if "Change Type" has been done on the balloons first.
   
3. Pick Custom/Retrieve, and browse to the desired symbol file.
4. If the symbol has variable text such as \index\, the index numbers from the table will be filled in on the symbols. It looks like variable text that is _not_ found in the table is not editable. I'm looking for a work-around for that.
