Using Installshield 2015 with MSBuild 2013/15

I want to run MSBuild and have it automatically create an application installer at the end of the build using Installshield 2015. We already pay for the professional version, so I do not want to use the LE version for Visual Studio since it is limited. I know that this can be done using a 3rd party build automation tool, but wanted to see if this was doable without using another build automation provider.

Currently, we run builds, then somebody grabs the files needed, open installshield, and runs it. Before working here, I used Automated Build Studio, which is no longer supported by Smartbear.

Please advise.
