Can I upload our logger in some directory (e.g. in C:\loggers) instead of adding to repository - i.e. upload file/s manually in settings panel ?

Why it's needed:

I developer of X tool for Visual studio (build/events etc.), in new version this tool should work also through msbuild for CI support and any custom build steps.
Also planned use CI for our project with AppVeyor. However, this project also uses self assembly and needed our lib & script for building...

On some our server with TeamCity(for example) of course we can manually place a some tool, but for web CI services this possible only with repository...

I already tested with AppVeyor - all works well :) especially thanks for VSSDK references ! AppVeyor won with this item... it's very easy for our project :)

so, for example:

• I added our library in cloned repo
• In settings of AppVeyor I set next script for build with our logger (CI.MSBuild.dll):

_

nuget restore vsSolutionBuildEvent_2013.sln 
   & "C:\Program Files (x86)\MSBuild\12.0\bin\msbuild.exe" "vsSolutionBuildEvent_2013.sln" /verbosity:detailed 
       /logger:"C:\Program Files\AppVeyor\BuildAgent\Appveyor.MSBuildLogger.dll" 
       /l:"C:\projects\ci-cfg-vssbe-naost\Build\bin\CI.MSBuild.dll" /m

And... result:

git clone -q --branch=ci https://bitbucket.org/3F/ci_cfg_vssbe.git C:\projects\ci-cfg-vssbe-naost
git checkout -qf b71f4a57f682082e1072ee9515fca103b979ae34

so, all works... but i not planned store this lib with sources... because CI it's additional story

If this feature not available at this time - please add any variants for simple adding any files in some directory for a custom build. I think it will be helpful for any cases...
or i can access to vm with shell ? where to look ? maybe also exists ftp access ?

i think later i'll also test variants with your webservice ~ submodules/subtree/subprojects... need to think, but

Anyway, Thanks for your great service.

ah yes., key to msbuild - '/m' probably not working, i have a notice:
