[WINDOWS] Multiple mods, one command line

In the HWRM launcher you can select multiple mods at once. How do you do this on the command line? Does the order of the mods matter? Thanks.

-mod mod1.big,mod2.big
The order of the mods matters - when there is a same file in both .big files, one will override the other (but I don’t remember if the file in the second mod will override the first or the first will override the second )

And it seems that the two .big files must have different TOC names, or there will be only one .big file read by the game.

Is it possible to stack multiple -moddatapaths?
