IANAP stand for I Am Not A Programmer, but I think this is what you need. Let me know if that's not gonna do it, though, and I'll see what I can find for you.

To modify a Task List item

To modify the left task frame and change the description that displays at the top of the workspace for the tasklist item, you need to modify the Left-XXX-Main.htm file in the particular module's folder.

Caution! Create a backup of your existing files before making any changes to the iMIS desktop.

1. Open Windows Explorer and navigate to the \framework\HiRes\feature folder, where feature refers to the area of iMIS that you want to modify.
2. Open the LeftXXX.htm file for the module in an HTML editor or Windows Notepad, where XXX refers to the area you want to modify. For example, the framework\HiRes\Customers\LeftCust-Main.htm file contains information about the links that display for the Customers task frame.
3. Scroll down to the part of the file that resembles the following:

<table border="0" cellspacing="0" class="lefttable" align="center">

			<tr>

				<td class="leftheading" nowrap><img src="../../images/left_heading.gif" border="0" align="absmiddle">&nbsp;Customers</td>

			</tr>

			<tr id="asimanagecust" style="display:none" onmouseout="unframe('asimanagecustlink1');"

				onmouseover="frame('asimanagecustlink1');">

				<td id="asimanagecustlink1" class="navlinkleft" onclick="LeftActivate('asimanagecustlink1','navlinkleft');

								SetTask('Manage customers'); CheckNavState(); SetWinLoc('iMISwin:iMISMEM.Name-ExecPortfolio');">

					Manage customers

				</td>

			</tr>

4. Scroll to the line that contains the menu item you want to modify, and find the SetTask value near the end of the line. This text controls the task description that displays at the top of the workspace. Make your changes.
5. Save the file.
