sorry no - that´s not possible and there are several reasons for that. The main reason is, that the support will be much more difficult, when nobody know where which files/packages (physical) are located … therefore exist exact specification from ASOBO, how and where such packages must be installed. This is a recommended rule right, and you can break that rule but then we loose also the support at ASOBO.
Second important reason is, that some sceneries and/or addon-aircrafts (like your example the AS CRJ) expect a specific path in an specific folder. When this path is renamed, moved somewhere else - you can´t update it because the installed does nothing know from your structure, your filenames.
Again, all of these solutions makes the support much more difficult because you “break” the standard and the support stuff needs much more time to find out where, what happened and possible why?
In other words - AddonLinker are not official supported by ASOBO, same for us - we also don´t support this kind of software but it´s up to you of course, to use it. Last there are standard-paths and standard flows, to find out where the community folders are, on which sim-version - we keep this standard flows but also here, it´s up to you to change this flow but than it´s unsupported.
Hope that helps and make something more clearer,
