property expansion in update defintion / refactor defintion text box

I have a variable in the project variables called 'wsdl' which contains the URL for some service.

When I try to update definition using property expansion
${#Project#wsdl}

I get the following error copied below.
1. Is it not possible to use property expansion in side update/refactor.
2. the reason this is an issue is because if you are using variables for your endpoints, using a literal WSDL will add another endpoint in service endpoints (which is not what I expect).
