C# MDL LOAD AppName,,unique from directory

I've discovered that in order to load/unload C# applications I must 

MDL LOAD app_name,,unique
clr unLOAD domain unique

This is great, but I end up adding quite a few dlls into mdlapps.  I would prefer to load my apps from a directory for the sake of organization.  

Is there a way to load apps from another directory using this syntax, e.g. mdl load ./folder/app_name,,.unique

Thank you for your insights.
