Proposed Cross Sections - File Path with space

When attempting to run proposed cross sections (through project manager), I have found that the define variables section will not accept files that have a space in them. Through trial and error I have found that files referenced elsewhere throughout the cross section run will accept files with spaces, and it is only in the define variables section that will not. Is there a possible workaround for such a situation? I have the log files for various trials I ran, but I don't want to clog the post with all that text.
