I played around with it myself a bit. You can create a smash config yourself by having the tool create all the record categories from the ESMs/ESPs which is probably better as SSE settings are eventually not compatible with / the record categories different from Fallout4. However I did not succed in creating anything like a bashed patch. All I got (which is already nice) is a smashed patch that combines settings from different esps which then can be disabled. So for now, all I achieved is to reduce the amount of esps with mator smash. If only there was a good guide on how to modify the smash configs to get it working...
