Windows store APPX package install file in different location

  appx, windows

So I have recently developed an app for the windows store, I packaged it into an APPX package. The problem is that windows auto installs it into a non-accessible folder meaning I cannot reference .exe and .pdf files.
Is there a way to make it always install 2 files in the same place, for example the two files which need to be edited install on desktop and the rest of the app in the usual install location?
Can I do this using two separate .APPX files?
