I will do this, but I caution you to take care.
I will not consider doing the same thing to all my graphics and presets.
Keep in mind that I have almost 5000 presets. Even with search and replace tools, making even simple changes to all of them is work I won’t do without a very good reason.
Not to mention the time it would take to go into all my source, make changes, export, and do post on the graphics.
Please don’t take my time and effort lightly.
