Can the soapui pro 2.5 global settings "Script Library" be a search path?

Can the soapui pro 2.5 global settings "Script Library" be a search path?
I'm thinking along the lines of something like (say) ${projectDir}/bin/scripts:~/soapui/bin/scripts:${workingDir}/bin/scripts, where ${projectDir}/bin/scripts might be
a library specific to a project and so forth. (The example's a little artificial, unfortunately.)
My guess is "no", but it doesn't hurt to ask.
