I second this. Or better yet, implement wildcards in the path names in grouping rules and saved groups. I use Discord in a saved group but every time it updates (which is often) it breaks the group because it changes the subdirectory with every new version, and I have to manually re-add it to the group.

For example, the path to Discord currently looks like this: 

C:\Users\<user>\AppData\Local\Discord\app-1.0.9200\Discord.exe

Ideally it would be nice to be able to use a wildcard like this:

C:\Users\<user>\AppData\Local\Discord\*\Discord.exe

I have the group pinned to the taskbar and this would allow it to continue to launch after updates rather than breaking each time. I understand the potential issues with allowing wildcards anywhere in the path, so perhaps limiting their use to the immediate parent directory of the process while still requiring the full path otherwise would be the best approach.

Edit: I see this was already suggested here. I do hope this can be implemented at some point.
