There's a quick way to handle this, with DAZ Packager.
It's an open source tool to create DIM usable ZIP files of any product.

Grab it either here via Renderhub (you'll get notifications of updates that way) :
https://www.renderhub.com/raph4/dazpackager

or keep an eye on the project page on Github here:
https://github.com/raphaelbouvigne/DazPackager

The tool is "drag'n'drop" so to speak. I use it by keeping a shortcut link on the desktop, and use it by dragging ZIP files that it can use or directories. It can do batch work too if you drag'n'drop multiple ZIP files too.

It asks you to provide either a ZIP file with the following contents, for example :
Content/
People/
and so on.
Or it can just be a top level content directory like People/ or Environments/

Or you can hand it a directory That contains the People/ or Environments/ stuff for example.

Thus, if I take the following files that Meipe provides here as updates:
G9_DCK_2025.zip
G9Dicktator_Inflate2_Scale2_Fix.zip
"G9Dicktator_WildBreeds (little fix).zip" (my quick edit of the material paths in the presets posted in another thread)

All three have "People" and/or "data" directories in them at the top level. DAZ Packager produces
DP95081450-01_G9DCK2025DIM.zip
DP96779975-01_G9DicktatorInflate2Scale2FixDIM.zip
DP97389731-01_G9DicktatorWildBreeds(littleFix)DIM.zip

Those three new files can be dropped in to the directory that DIM looks at when installing new products. They come complete with manifestos and meta data.

All the script fix ZIP files can just be drag'n'dropped on to DAZ Packager. The old files are left untouched and new DIM-ready files are produced and saved right alongside them.
