Enable alternate versions of the SWMM engine within ICM
I would like to have the option to use a different version of the SWMM engine to be run instead of the latest Innovyze version. In some cases this is required, but it is often very helpful to confirm the results from previous versions.
Perhaps a way to read the older OUT files from EPA SWMM in the SWMM simulation engine? There have been over 35 versions of EPA SWMM5 and we use the current version of EPA SWMM5 in the simulation engine.
This may be hard as the SWMM engine in ICM has to be able to work with all of the bells and whistles of the ICM GUI or UX. There are also about 35 SWMM5 versions but certain ones such as SWMM 5.0013 are more important historically.
