Hello,
I made a tool for 3D artists, hardsuface guys, those love to add decals in Zbrush quickly.
The process is super simple
Just drag and drop and split to use it like subtool.
This is a link to show you a small demonstration at 1min 28

You can try the free pack (9 DECALS)
then if you’re interested i put the link for the full pack (42 DECALS)
and my gumroad profile
Hope you will like it.
May be i should called that ZDECALS 
Let me know.
Have a great day.
Cheers.
