Mass Update Namemap Properties

Is there some method to mass update the properties of namemap fields?

For technical reasons, our development department had to change the ID value associated with tons of fields in our web application. The new ID value is the same as the old but now has "_input" appended to it. For example, NameFirst is now NameFirst_input. We have hundreds of fields mapped using idStr property and I need all of them modified to have "_input" added to the expected property value.

Is there any easy solution to this? Any way to write a script to handle this? Is there any way to even get a list of all fields in the namemap that use idStr as one of their identification properties?

Here is how the field change:

Edit to add:

I just realized the namemap file is basically an XML file. If I write some code to update this raw file will it corrupt it in TestComplete? I might be able to write some code to update the values I need.
