Sue,
You can use Grep Find/Replace to paste your graphic into your layout.
Open up Find/Change and select the GREP tab.
Assuming that the sequence numbers are digits only and that you have one space between the digits and the product name, you could try the following steps.
Copy the dingbat to your clipboard then use the following find/replace:
Find:
^(\d+)( )
Replace:
$1$2~C
^ The caret is used to signify “look at the beginning of the paragraph”
() Items within parentheses are considered subexpressions, which are important for the replacing aspect.
\d References any digit
+ Indicates one or many of the previous character.
$1 Indicates sub-expression 1
So to spell it out. Look at the beginning of a paragraph for one or more consecutive digits, as sub-expression 1, with a space immediately following, which is sub-expression 2. Then replace with the results of sub-expression 1 followed by sub-expression2 followed by the contents of the clipboard (your dingbat).
You can modify this to suit space before and after the dingbat.
Let me know if this works. If not, id me more than happy to help with additional questions. If you need to send any examples my email address is my first name AT my last name .us (all lower case).
