Change variable bool to string

[t1701]

I have a report created a while ago which uses a bollean variable for conditional formating. It allows 2 versions of a report to be run.
Now they have asked for a 3rd version which means I have to change the boolean variable to a string variable.
If I create a new string variable, I need to go through every object in the report and document what the bool variable does and it controls a lot of formatting.
Any suggestions?

You could edit the report spec xml by hand by copying report to clipboard then pasting into a text/xml editor.  Add the new string variable first with a different name, then in the xml delete the old boolean variable and rename the string variable, then do a global search and replace for the conditional formatting substituting the new values of your string variable for the true/false values of the boolean.  Once you're done, copy the text file to clipboard then in report studio select Tools -> Open Report from Clipboard.
