Path settings can be specified within DIM without any problem, but this needs to be done manually each time you install new content. I have multiple runtimes listed, as well as my DAZStudio content folder, under the preferences. Where V4/M4 and morph packages are concerned, everything must be installed into the same runtime, and definitely no multiple instances must appear anywhere else. Every time a morph package is installed, the batch files must be rerun to activate those new settings. Otherwise, they might not show up or work correctly.
