Mapping paths/Windows paths compatibility

Hello, I've tried to find information about it, unfortunatelly it does look like a big issue. Im working with different people and they are using windows to work. We all use dropbox to synchronize our files. To make sure our paths are the same in all softwares, I've found workaround on windows to share folder, where dropbox is installed, to myself (it creates //PC_NAME//... network path )and then map network as T:/ letter, so all absolute paths are the same, no matter where dropbox is installed. However, how to recreate it with linux, as there are no letters in paths, can I create some "fake" path? I would love to map my dropbox directory on linux to the same letter or tell somehow linux to always change "T:/somepath/somepatah' for /mydironlinux. Script that is changing paths or using only relative paths is not solution, as often in different sofwares you are choosing files in browser, changing those paths to relative might be huge pain if file is far away from current dir, and not every software support it
