Is there a simple way to change part of the property value in a bunch of files rapidly?  I know about using task scheduler to update values, but as far as I know, you can only update the entire value that way, not part of it.  For example, lets say my standard numbering system is AAA-XXXX, where XXXX is a sequential number that must remain, but AAA needs to change to BBB.  My plan is to use SolidWorks Explorer to individually paste the new piece of text into each existing value, but I'm hoping there's a quicker way - perhaps a macro using substring?.
