<div>Can you expand upon this question a bit? I&#39;m curious if there&#39;s a less hackish way of doing what you want to do. Under what circumstances do you need to add the leg variables? Also, can you give us the big picture? What&#39;s the problem you&#39;re solving?</div>

<br>
I thought I read somewhere that this was possible, but I can&#39;t find it now...<br>
<br>
I need a way to find-and-replace within a variable.  So, for example,<br>
I want to take variables that have values like this:<br>
<br>
123abc123abc<br>
abc123abc123abc<br>
<br>
...and do a find/replace of the &quot;abc&quot; with &quot;xyz&quot; so the variables<br>
would now return:<br>
<br>
123xyz123xyz<br>
xyz123xyz123xyz<br>
<br>
The use case I&#39;ve run into is that I need to add leg variables to<br>
group_call.  In my case, group_call can return any number of members,<br>
so I figured I would just replace the first &quot;[&quot; with<br>
&quot;[variable-I-want-to-set=...&quot;.<br>
<br>
Thanks for the help!<br>
