Replace parameters for file path defined in Constant value Send Email function

As I know in Project Explorer, there have two icons provided for replace the parameters after copy and pasted the whole project to the production environment server. However it does not cover all the parameters, such as file path defined in Constant value, the parameters in Send Email function. Therefore we need to double check each of every single parameters in WF, DF to ensure everything correct. It is time consuming! May I know any new deployment function will come soon or planned in the roadmap?
