Customizing Default Install Location

[RABIDYOTE]

So I have my computer set up to where the majority of my programs should be installed on my D: drive, and leave my C: drive mostly for Windows itself, in the event I have to reinstall it. I previously set the default install location to be D:\Programs\%PACKAGE%, however, I recently noticed that it is interpreting this as the full package ID rather than just the name, as I thought. So as a result, I have a ton of duplicate installation entries from when I initially installed my programs manually, and when UniGetUI updated them. I did find the file that would allow me to customize this further, however I don't know the syntax that would allow me to just set the install path as the package name by default, nor do I know if this is even supported.

Does anyone happen to know how I would set it so that, for example, Notepad++ installs as just that and not Notepad++.Notepad++, or am I going to need to go through and manually set all the install paths?
